She's about 9 pounds. She's very affectionate but she's constantly trying to cross my path to stop me from proceeding while barking and snapping at me. She does the same thing to my 4 years old small dog who is very peaceful. She's been with us for almost a week. I'm training her in my backyard to walk on a leash giving her treats when she walks by my side. However, she still tries to get in front of my feet to stop me. She does that even inside the house. I'm crate training her which she seems ok with it. She has lots of toys and a comfortable bed in the crate. The crate is for a medium size dog, so it's a bit too big for her. However, she only had 1 accident because I take her out on schedule. I just want her to stop snapping/nipping at me and my little dog. Any suggestions?
