Summer is here, and the heat is unavoidable, for us and our pets. Do you know how to tell if your pet is overheating or showing signs of heat stroke? You may have noticed a decrease in your own energy as the heat rises, or general exhaustion from being in the heat for too long. The same is true for your pets, although the effects of heat are harder to recognize in them. Even when preventive measures are taken, it is important to monitor an active dog or daring cat,who insists on exploring the great outdoors. Here’s how to keep your pets safe during the summer in Arizona.
Overheating vs. Heat Stroke
A lot of people think that overheating and heat stroke are synonymous with each other. However, they are not the same. Overheating (or heat exhaustion) is the stage before heat stroke in which the body is showing signs that it is too hot and measures should be taken to prevent further harm. Heatstroke (or hyperthermia) results in heat injury to tissue. Both conditions are serious, but if your pet has a heat stroke, it is important to get immediate veterinary attention.
Signs of overheating in dogs:
- Rapid panting
- Dehydration / excessive thirst
- Increased heartbeat
- Elevated body temperature
- Disorientation
- Changes in gum and/or tongue color
Signs of heat stroke in dogs:
- Excessive panting
- Excessive drooling
- Collapse / Coma
- Vomiting
- Diarrhea
- Abnormal behavior
- Stumbling
- Muscle twitching / Seizures
Signs of heat stroke in cats:
Cats will exhibit many of the same signs as dogs, like panting or drooling, but often you also need to watch for more subtle signs like drinking unusual amounts of water or excessive grooming. Anxiety, pacing, and nosebleeds are also symptoms of heatstroke in cats.
If you’re worried, the best thing you can do is call your vet.
Heat stroke can be deadly in Arizona, so if it ever seems like your pet is unable to cool themselves down, please don’t hesitate. Call your vet right away.
