Colpo di Caldo nel Bulldog Inglese

Bulldog
Colpo di Calore

Ogni Bulldog Inglese è una vittima potenziale del colpo di calore, il sistema respiratorio mette il bulldog a forte rischio in questa grave patologia.Vie aeree più corte significa minore possibilità di raffreddare l'aria che il bulldog introduce nel proprio corpo. I bulldog inglese non traspirano. Solo il 2% (le zampe) del loro corpo è coperto da ghiandole sudoripare.Il loro solo mezzo di ridurre l'accumulo di calore nel corpo è di ansimare. Tutti i possessori di un bulldog devono sapere che molte volte il caldo,la privazione di acqua, l'eccessiva umidità,,la mancanza di acclimatamento, l'esercizio,l'obesità e i problemi cardiovascolari possono essere fatali per il bulldog.

SINTOMI DEL COLPO DI CALORE NEL BULLDOG

Il bulldog inizia ad ansimare con affanno Il ritmo cardiaco è accelerato Il bulldog inizia a "ruggire"-Il suono è simile al respiro di un grave asmatico Inizia ad apparire stanco e stressato La lingua del Bulldog è floscia e molto arrossata La pelle all'interno dell'orecchio del bulldog diventa rossa Le membrane mucose del Bulldog sono congeste e rosse La temperatura del corpo del bulldog aumenta(temperatura normale 38.6),superando i 41°C Ipersalivazione Potrebbe esserci diarrea o vomito Il bulldog è sotto shock le membrane mucose e le labbra del bulldog diventano grigie Le vie aeree si gonfiano e la gola si riempie di schiuma o bava bianca Il bulldog diventa rapidamente esausto Potrebbe morire

COME PREVENIRE IL COLPO DI CALORE

Fare molta attenzione nelle giornate caldo-umide con poca ventilazione. Fare moltissima attenzione al trasporto in automobile da aprile a settembre Mai lasciare il bulldog chiuso in macchina anche se il caldo è leggero. Ricordate che la temperatura all'interno di una macchina chiusa esposta all'azione diretta del sole può superare i 49°C in meno di 20 minuti anche quando la temperatura esterna è di soli 24°C. Non permettere al bulldog la permanenza sotto i raggi diretti del sole. Controllare quando gioca e determinare quando è ora di fermarlo Limitare la esposizione a una temperatura considerata leggermente calda Considerare la prossimità del bulldog al suolo surriscaldato soprattutto se è asfalto o cemento Non permettere al bulldog di permanere all'aperto durante le giornate assolate Quando fa caldo non eseguire esercizi o lunghe passeggiate e tenere il bulldog in casa durante la parte centrale della giornata Avere sempre a disposizione acqua fresca in abbondanza per dissetarlo e se necessario per bagnarlo Utilizzare in casa condizionatori di aria e ventilatori. Se non c'è il condizionatore di aria in un giorno caldo possiamo riempire una vasca per 1/3 di acqua e lasciamo che il bulldog si riposi in essa oppure stendiamo il bulldog su una borsa di ghiaccio in un pavimento a piastrelle, chiudiamo le tapparelle e le finestre , prendiamo un ventilatore e lo puntiamo su qualche secchio di ghiaccio.

COME COMPORTARSI COL COLPO DI CALORE

Il colpo di calore è un urgenza,il bulldog va raffreddato il più rapidamente possibile e non c'è tempo per aspettare il trattamento veterinario. Interpellare il veterinario telefonicamente. Il bulldog va lasciato sdraiato finchè non ha superato il malessere, Se proprio necessario mettere un asciugamano freddo e bagnato sotto il bulldog per il viaggio.

ABBASSARE LA TEMPERATURA CORPOREA:

sempre assicurati di avere ghiaccio e acqua a disposizione durante la stagione estiva. Versare acqua fresca sul bulldog, applicare il ghiaccio intorno alla testa , sotto la coda intorno al retto, sull'inguine sopra le arterie inguinali e sotto le ascelle.Il ghiaccio è avvolto in un panno e non a contatto diretto con la pelle. Portarlo in un luogo con l'aria condizionata e posizionarlo di fronte a un ventilatore per aumentare l'evaporazione dell'acqua e la dissipazione del calore,se non è possibile portarlo all'ombra e ventilare con un giornale Se possibile immergerlo in acqua fresca,non troppo fredda o ghiacciata perchè la vasocostrizione periferica non permetterebbe una buona dissipazione del calore . Se no fare la doccia fredda col bulldog in braccio,facendo moltissima attenzione a che non vada acqua sul muso e quindi davanti alle narici. Strofina un pezzo di ghiaccio sulla sua lingua per 10 secondi,interrompi per 10 secondi, strofina e interrompi etc. Avvolgilo con asciugamani bagnati sostituendoli quando diventano caldi. Massaggiare il bulldog (migliorare la circolazione sanguigna aiuta il raffreddamento). Si può spargere dell'alcool sullo stomaco e sulle piante delle zampe per aumentare l'evaporazione. Utile puo essere un clistere di acqua fresca,che deve essere solo di alcuni gradi più bassa della temperatura corporea,ed effettuato da persona esperta Somministrare farmaci(iniezione di corticosteroidi per contrastare il collasso cardiocircolatorio e la tumefazione della gola) previo accordo con il veterinario, in mancanza possiamo utilizzare le bombolette spray a base di corticosteroidi degli asmatici. Controllare la temperatura che deve abbassarsi gradualmente,un abbassamento troppo rapido potrebbe avere gravi conseguenze. Per pulire le via aeree spruzza del succo di limone in gola, vi odierà, ma il succo di limone permetterà di espellere la bava o la schiuma e di schiarire la gola(se no usare una bibita al limone come il 7up). Non permettere di bere molta acqua perché potrebbe provocare il vomito o essere aspirata nei polmoni. Interrompere le procedure quando la temperatura rettale è scesa a 39°C. Quando il tuo bulldog sta meglio lascialo in un luogo tranquillo ma controllalo attentamente. Appena possibile é necessaria una visita di controllo dal veterinario in quanto il colpo di calore può lasciare gravi conseguenze a carico di diversi organi.

NOTA:

lo stress,nel bulldog, può provocare gli stessi sintomi del colpo di calore e va trattato nello stesso modo.

How to Prevent Heat Stroke in Dogs

 

Hot summer weather can be more dangerous to dogs than many pet owners realize. When a dog's internal temperature is raised too high (generally about 106 degrees F), a chemical reaction occurs that actually breaks down the cells in your pet's body and can result in death. But, thankfully, there are some simple common-sense steps you can take to keep your dog healthy and prevent heat stroke.

Ensure that any dog kept outdoors has plenty of water and shade. If the weather is unusually hot, take time to check the outdoor temperature in your pet's area. It may too hot in some locations to leave your pet outdoors regardless of providing water and shade.

Restrict outdoor exercise to the early morning and late evening when temperatures are cooler

Carry water with you when walking your dog. Watch your pet carefully for indications that he is over-heating, such as heavy panting, loss of energy, and any obvious weakness or stumbling. If your pet begins to show signs of heat suffering, stop in a shady spot and give him some water. If symptoms don't subside, take him directly home and seek veterinary care.

Never, never, never leave your pet unattended in a parked car. Even if you park in the shade and leave the windows open slightly, the internal temperature of your car can heat up and put your dog in fatal danger within just a few minutes.

Equip your car with window shades if you are planning a long car trip with your dog. Bring water and/or ice cubes along to help keep your dog hydrated and cool.

Tips

You can purchase cool pads for use in the dog's crate or in your car. When soaked with cool water, they keep the temperature down. Bandanas can also be used in this way.

Pharmacies carry athlete-grade ice packs that can be frozen and create little mess. Additionally, they can be applied directly to specific areas.

To help your dogs feel cooler, fill a spray bottle with water and squirt him. Just make sure you don't spray her!

If your dog is showing signs of heat stroke, use a rectal thermometer to check his temperature. If it is approaching 105 degrees, put your dog in a cool bath (or at least sponge him down) and call your veterinarian immediately. When your pet's temperature drops to 103 or 104 degrees, you can take him out of the cool bath so his temperature won't drop too quickly

Heat stroke in dogs: A retrospective study of 54 cases (1999-2004) and analysis of risk factors for death.

The medical records of 54 dogs presented to the Hebrew University Veterinary Teaching Hospital and diagnosed with heat stroke were retrospectively reviewed. Data abstracted included history, clinical and clinicopathological signs at admission, treatment, disease progression, and outcome. Exertional and environmental heat stroke were present in 63% (34 of 54) and 37% (20 of 54) of the dogs, respectively, and 78% (42 of 54) were examined between June and August. The mean temperature and heat discomfort index in the particular days of heat stroke were significantly increased (P < .001, P < .001, respectively) compared with their corresponding average daily values. In 27 dogs the body temperature was > or = 41 degrees C (105.8 degrees F). Belgian Malinois (15%, odds ratio [OR] = 24, 95% confidence interval [CI95%] 8.2-64.5), Golden and Labrador Retrievers (21%, OR = 2.08, CI95% 0.95-4.2), and brachycephalic breeds (25%, OR = 1.7, CI95%], 0.81-3.21) were overrepresented, whereas small breeds less than 8 kg were underrepresented (2%, OR = 0.08, CI95%, 0.002-0.48). Thrombocytopenia (45 of 54 dogs) and prolongation of the prothrombin (PT) and activated thromboplastin (aPTT) times (27 of 47 dogs) were recorded during hospitalization. Disseminated intravascular coagulation (P = .013) and acute renal failure (P = .008), diagnosed in 28 of 54 and 18 of 54 of the cases, respectively, were risk factors for death. The overall mortality rate was 50%. Hypoglycemia (<47 mg/dL, P = .003), prolonged PT (>18 seconds, P = .05), and aPTT (>30 sec, P < .001) at admission were associated with death. Serum creatinine >1.5 mg/dL (P = .003) after 24 hours, delayed admission (>90 minutes, P = .032), seizures (P = .02), and obesity (P = .04) were also risk factors for death. Heat stroke in dogs results in serious complications and high fatality rate despite appropriate treatment.

Intrinsic thermal resistance of the canine brain

Hyperthermia above a critical threshold results in multisystemic changes that include neurological manifestations of heat stroke. It is unknown if the latter represents an intrinsic thermal sensitivity of the CNS or whether injury is secondary to physiological responses of non-CNS origin. To address this issue, the present work examined functional, structural, and biochemical changes in the CNS of dogs subjected to a thermal dosage immediately below that which induces disseminated intravascular coagulation with secondary multiple organ injury. The experimental approach is previously reported, inducing a 42.5 degrees C, 90 min, whole body hyperthermia while preventing other physiological responses to treatment, including respiratory alkalosis and significant reductions in mean arterial pressure. Functional analyses included neurologic examinations and brainstem auditory evoked potential recordings in the post-treatment interval in both hyperthermic and euthermic control populations. Biochemical and structural analyses examined the expression of 70-kDa heat shock proteins, cytokines, markers of astroglial and microglial injury/activation, evidence of vascular endothelial damage, and evidence of neuronal and axonal injury in brain between 0.5 h and 8 days from the end of the treatment. The only significant change associated with treatment was induction of the major inducible 70-kDa heat shock protein, this being most prominent in the cerebellum with maximal expression at 6 h and a return to baseline by 8 days.Collectively, from these results we suggest that the canine brain is intrinsically resistant to sublethal hyperthermia such that when CNS lesions occur, they do so in the presence of other physiological derangements.

Heat Stroke in the English Bulldog

 

Medical Emergency Betty Fisher I had a really big scare today, the first time this has happened in over 35 years of owning many bulldogs. My son took Mischief, a 19 month old puppy and a very good breather, for a walk. She is a dog that gets very excited about adventures. About half an hour later he called from about 5 blocks away. Mischief was hyperventilating and in distress. She was panting but making a very distressed sound and it was obvious that her throat was constricted and she was having to force air into her lungs. I raced down immediately where he was sitting in the shade with her, poured a jug of water on her and offered her water to drink. She improved momentarily but started making the same sound. I put her into the truck and raced to the vet, only 2 blocks away fortunately. Getting her out of the truck and going into the vet stressed her even more and her tongue was purple by this time. I yelled, “I’ve got an emergency”, raced through to the back, placed her in the tub and started running cold water over her. The vet gave her a mild sedative to relax her, cortisone to reduce the swelling in her throat and oxygen. Her temperature was 105! We also cooled her down by rubbing her with alcohol. In less than ½ hour she was relaxed, temperature back to normal and I could take her home. She could have easily died instead! Mischief was excited and being a flat faced breed her need for oxygen exceeded her capacity. As she struggled for air her throat became constricted, panic and the need for more air made her struggle harder, the palette and airway swelled from the strain of trying to bring in more air. A vicious cycle was set in process. The harder they struggle to breathe the more inflamed the throat tissues become. As the dog takes in less oxygen more heat is retained increasing the dog’s need to pant. This was caused by too much excitement, not from the weather hot but the result is the same. These episodes can happen more easily on warm days. It is very important to carry water at all times, and ice cubes in warm weather. Any time your dog starts to become warm is the time to act, don’t wait until they are in distress, it may be too late. Soak your dog down, give them ice cubes and try to keep them calm.

Heat Stroke in the English Bulldog:

 

By Betty Fisher Heat is probably the number one danger to the Bulldog and all of the other flat-faced breeds. A dog’s primary cooling mechanism is the ability to pant and dissipate body heat. Short nosed dogs have a reduced ability to cool by panting, coupled with the fact that many of them have a reduced breathing capacity caused by any one or all of the following: pinched nostrils, elongated soft palette, small trachea or extraneous tissue in the throat. Additionally the Bulldog is a very heavy boned, dense bodied dog. When this mass becomes overheated it is very difficult to reduce that temperature. Dogs, in general, are far more susceptible to heat stroke than people. In view of these facts the best way to treat overheating is to never let it happen! Prevention is by far a safer and more effective way to combat enemy #1, heat. Heat stroke is not just the enemy of short nosed breeds. Every summer dogs of all breeds are overcome in cars, herding bulldogs collapse, dogs playing in the sun can get heat stroke and hunting or field dogs suffer from too much heat, humidity and/or excitement. Heat Plus Excitement Heat combined with excitement or stress is the biggest danger to our dogs. When our bulldogs become excited they begin to pant. When they become warm they begin to pant. Since the Bulldog cooling system is inefficient you can quickly exceed its’ capacity and then the bulldog is in trouble. How hot does it have to be for the dog to be in danger? The temperature can be down in the 70’s and our bulldogs can be in danger. Temperature, humidity and the bulldog’s total breathing capacity are all factored in the dangerous heat equation. The amount of air circulation, whether the bulldog is in the shade or the sun, how stressed he is all make a difference in the effect of heat plus excitement. Danger Signs!!! How will I know when my Bulldog is danger? Some danger signs are: Unusually sluggish or unresponsive Pale or dark red gums, may be very dry Erratic breathing Glazed eyes Vomiting In the final stages the dog will suffer convulsions and unconsciousness If you observe any of these symptoms it is imperative that you take action immediately! Get your bulldog into the shade and apply cold water or hose gently with a continuous stream of cool water. Submerge in a tub of cool water if possible. If possible apply ice packs or cold towels. If your bulldog is conscious allow him to drink small amounts of water or lick ice cubes. Do not force him to drink. Get veterinary attention immediately. You may save his life! Prevention Prevention of heat stroke is much easier and very much less likely to result in the loss of your bulldog. Begin by becoming aware of the weather. Observe your bulldog when he plays or is warm. How does he act? How much does he pant? What color are his gums when he is panting? The more you know about your bulldog’s normal actions the quicker you will realize when he is in trouble. Good heat management will keep your bulldog healthy and safe. • Be sure there is shade every place you keep your dog. • Don’t take your bulldog in the car during the warm hours unless absolutely necessary. • Monitor the dog’s playing, especially with children. Dogs will not stop just because they are too warm. • Use fans placed at the dog’s level. If you bulldog still chews protect the cord from his teeth by placing it under or behind furniture or running it through a piece of PVC piping. You can also place it behind a gate or exercise pen. • Give your bulldog plenty of cool water. My outdoor water pan is a cement mixing plastic trough from the home improvement store. Keeps the water cool and you don’t run out if you should neglect to fill it everyday. Your bulldog can use it like a wading pool it he wishes. • Use large indoor water bowls. Never leave your bulldog any place without access to cool water. • Provide ice cubes on warm days. Not just a few, entire trays of ice. • Provide a child’s plastic wading pool. The 4’ diameter allows two or three dogs to play and has sides low enough for bulldogs to go in and out easily. • Soak your bulldog when he starts to pant. Don’t wait until he is panting heavily. Prevention of heat exhaustion is far easier than treatment. Put him in the tub or under the hose and SOAK. Many people tell me their bulldog doesn’t like to get wet. Well, tough. You are the caretaker of your bulldog and you are the responsible adult. If your bulldog needs to be wet to protect him, put him on a leash and soak him down. I praise, saying “let’s cool down, wow doesn’t that feel good?” Make them believe this is wonderful and give a cookie after you finish. Yes, he will go back into the house wet. Saving his life is more important than saving the furniture. Put him in the kitchen with a fan. You can find a way to deal with a wet bulldog. • Riding in the car takes special preparation. A parked car, with windows open a couple of inches can reach 120 degrees in less than thirty minutes! Carry a gallon-insulated jug of water at all times. Keep water in front of your bulldog at all times. There are plastic water dishes with a top that prevents the water from splashing out. One brand is Water Hole. Fill the dish with ice cubes. Put a wet towel down in the car. If your dog starts to pant, soak him with your water in the gallon jug. I have stopped at a gas station, grabbed the water hose and drenched a bulldog. Yes he goes back in the car wet. Carry a towel or two to protect the seat cover and also to use for wetting him if necessary. • I recently purchased a small oscillating fan at Wal-Mart for less than $10. It plugs into the cigarette lighter and keeps the air moving when the car is stopped at a light or whatever. There are also battery operated fans that can hang from a crate or exercise pen. • If you bulldog does get hot on you and his breathing becomes constricted or he is vomiting up white, thick foam, a lemon or lemon/lime soft drink will sometimes help loosen up the congestion. If this happens you need to find a vet, soon! • Recently I saw a non-bulldog owner using an ordinary garden sprayer, the kind with a 1-2 gallon tank with a wand sprayer, to mist their bulldog. Of course, the sprayer was new and never used for pesticides. Would be easy to carry in your car and use wherever you take your bulldog. • Purchase or make a cool pad. These pads are made of durable material and filled with the water absorbing crystals found in nurseries. When soaked for 30-40 minutes they will remain damp and cool for up to twentyfour hours. They are becoming available in bulldog supply catalogs. They can be used in the car, placed in front of a fan or used in crates or exercise pens. Common sense and good management will go a long way to keeping your bulldogs safe in hot weather. I live inland from San Diego in So. Calif. Summer temperature often reach 105 degrees plus and I have no air conditioning. There are fans in almost every room. The bulldogs have their own set of ice cube trays and often use 8-10 trays a day. On the really hot days I place wet towels on plastic in front of each fan. By following these practices I have never had a dog get into trouble, but I do admit to being fanatic about the care of my bulldogs in warm weather.
