Playing Dress Up

I have a silly question for u. Can clothing on a puppy change their personality? My puppy is usually pretty aggressive which we are working on. But when he has clothes on he's very sweet n humble. I'm wondering if u have ever heard of this before n if this is harmful.

Putting clothes on him takes him out of his comfort zone where he would otherwise respond with aggression.  Exposing him to a  wide  range of experiences could help teach him to adapt to your lifestyle. The same result could be achieved by you not tolerating his aggression. It is not a problem to dress him up but be careful not to let him get the upper hand to demand your attention.
