This is a pretty well-known thing, but important to repeat: never leave your dog alone in a hot car. Cars can quickly reach dangerous levels of heat, easily becoming 20 degrees warmer than the temperature outside. And leaving the windows open isn't enough to cool the car down to safe temperatures. If you have tasks at places that don't allow dogs, it's best to keep your pup at home or take him to daycare.

6. Cool Down With Frozen Treats Or A Swim 

Frozen treats are a great way to help your dog cool down on a hot summer day. You can make your own by freezing bananas, pumpkin, watermelon, or other dog-safe goodie. You can also buy canine ice creams at the store. Just make sure to take the extra calories into account for your dog's following meals.

Another way to cool down is going for a swim, but only if your dog can and enjoys it. That being said, even dogs who have the ability to swim can become tired, increasing their risk of drowning. It's recommended you use a canine life vest to be safe. Certain breeds have more trouble swimming and should not go in the water. should not go swimming. These include brachycephalic dogs, puppies, seniors, those with large and heavy heads, and those with short legs and long backs (like Basset Hounds and Dachshunds).

7. Beware Of Bugs & Critters

Summer is prime time for bugs and critters. Your pet should be protected from fleas and ticks all year, but particularly in the warmer months. Bees, wasps and hornets can also be an issue. Dogs are usually stung on the face or mouth, which often results in pain and yelping. But some dogs are allergic, which can be life-threatening. Signs of this include swelling of the eyes and face, difficulty breathing, excessive drooling, vomiting, diarrhea, weakness and collapsing. An allergic reaction usually occurs 10 to 30 minutes after the sting, so call your vet immediately if you believe your dog is having one.

Bugs aren't the only animals that become more active during the summer. Other critters - like snakes and skunks - do too. Snake bites can be very dangerous to dogs, especially if the snake is venomous. They usually occur on the paw or face and cause swelling. Contact a vet immediately if your dog has been bitten by a snake. Skunks are less dangerous, but cause smelly issues. When threatened, they use their scent glands to release their oily, sulfuric scent with a high degree of accuracy from 10-15 feet away. To avoid these issues, keep an eye on your dog when he or she is outside.

Be Knowledgeable

It's always a good idea to be prepared, just in case, and knowing the signs of heatstroke can save lives. If you see your dog excessively panting without resolution, it can indicate heatstroke. Other signs include dark red or purple tongue, difficulty breathing, glazed eyes, rapid heartbeat and vomiting.

Pro Tip: Brachycephalic breeds (those with short muzzles), overweight dogs, dogs with thick or heavy fur, and older dogs are more prone to heatstroke.
