I picked up a rescue puppy thats between 4 and 6 months old. Shes very shy and also very stubborn. I guess my question is has she already developed habits that she's not going to want to be broken from? shes very anti leash and rather than walk with me she just lays down then gets up moves 20 or 30 feet and lays down again.
also shes very shaky I don't know if its being cold(unlikely) or being scared. and she has yet to bark.
any advice would be awesome.
