What is a safe indoor temperature for a dog?

It depends on the breed of dog and if you live in a high humidity climate or a State with lots of hot sun like Florida for example. The hottest part of the day (at least in Canada) during the summer peeks at about 5 PM. Places such as Savannah dogs should be kept indoors until evening. If your dog is an outside dog they must have shade and lots of clean water. Dog houses don't count even though they shade the dog, but retain heat. The best method is to bring your dog in at the hottest part of the day (or, if you have a small dog then have a 'doggy door' allowing your pet to come and go as they like while you are at home.) When in doubt bring your dog inside 80 degrees or more and then let them out after it starts to cool down, but always keep an eye on them. If walking bring along a collapsible doggie dish (bought at any pet store) and take a bottle of water with you. NEVER let your dog run along side your bike. Dogs dehydrate quickly like people.
