I'm sure everyone has seen the argument by now that if you shave a double coated dog in the summer, it will actually make them hotter. The thought is that their coat provides insulation and actually works to keep them cool when it's hot, as well as warm when it's cold. My problem with this argument is that I haven't seen any real research that proves this concept, and the only "proof" I have seen is a thermal image of a shaved versus an unshaved dog. It's always like "look at how the shaved dog is red and the unshaved dog is blue so that means that the shaved dog is really hot" which obviously, is not how those images work. If you put a down jacket on a human, it would show up blue but that does not mean the human is cold when it puts the coat on. It just means the coat is preventing the body heat of the human from escaping and being detected. I understand that dogs have different cooling mechanisms than humans, but we don't rush to put down jackets on pit bulls or dalmatians when the temperatures rise above 80 so that they may have the same insulation as a husky. So my question is, is there any validity to the argument that shaving a double coated dog in the summer is bad for the dog?
