A. Dogs don't sweat in as many places as humans, but there is some heat exchange that occurs through the skin. It will depend on where you live, what activities your dog partakes in, and whether shaving seems to help her.
Some dogs can have trouble growing hair back, so if you are very concerned about appearance I wouldn't do it. Make sure you watch for signs of heat stroke such as lethargy and vomiting. Slowly acclimate the dog during hot months and do not take him/her out in the hot parts of the day. If you have any concerns about heat stroke, ask your vet.
