chelsea (15 weeks) is a very nervous wee puppy...she gets excited to see u but you cant go to her she backs away from u. she has to come to u after u reassuring her to keep coming towards you. she barks and growls at dogs...she has done this day one when i took her homeat 12 weeks...is this a nervous thing with her as well? i am planning on taking her to training classes. i want to have a bond with her like i do with my rottie sasha...me and sasha just have that bond ..my aunt suggested to spend at least 15 mins with sasha on her on and at least 15 minutes with chelsea no her own that way she isnt fighting with sasha to get in about me. any other suggestions??
