What you’ll need to do is adjust the time you would normally take your dogs for walks if your schedule will allow it—this might look like taking your dog out before the sun rises or shortly after it sets.

Keep Your Dog Hydrated

Water accounts for about 60% of your dog’s body weight. Making sure that your dog gets enough water each day is very important—especially on hot summer days. In general, a dog will need about 1/8th of a cup of water per pound of its body weight every day. When it’s hot outside, constantly monitor your dog’s water bowl so that you know when it needs to be refilled.

Your dog can also get some of its daily hydration from wet food if that is a part of its diet. Keep in mind this might slightly reduce the amount of water it needs each day, but this doesn’t mean you should provide any less water for your dog. On the other hand, if your dog’s diet consists of primarily dry dog food, it might need to have more water, as the dry food can be dehydrating.
