@TwinDogsDifferentMothers:
Our opinion is, you own your dog, you know if they are struggling under the conditions and exercise load that you work them at. If that is the case then you should take whatever steps are necessary to keep your dog healthy. There is nothing wrong with buying some extra equipment to be on the safe side no matter what anyone else says.
Absolutely agree with you. And some dogs will need it more than others.
