I have an older dog that has short hair and he gets cold so easily so I went and bought him one of these and he loves it!! He hasn't tried once to take it off!! So that should just tell you right there how comfy he is in it!
I swear I am not one of those people that constantly dresses their pet! ...but.. Especially for dogs with shorter hair, shirts like this can do wonders for keeping them warm in the colder months of the year.
