I think if you want them to wear clothes you have to start them out right when there a pup! When I first put a tee on Lillie she tried to bite at it, but I'm water bottle training her and I squirt at her and she stopped, she knows she cant do that and so far I have not had to squirt her anymore. She hates the water so this training works great for her.
I would try a light tee shirt, something not to heavy. |
