There is no medical explanation for this, some dogs just enjoy it. It might be the warm water, or they may like the taste. I can tell you that both my dogs do it, and one of my cats as well!
It won't be harmful to your dog, just don't let him ingest a lot of soap.
And if it's bothersome, then just shut the door.
I hope this helps
so if i put a buth bomb in the water close the door.... i was just wondering i there was any pack or health reasons why she does it.... i kinda think it is cute
no not really, i think they just enjoy being close to you
but don't let them eat the bath bomb!
will do thank you
