Keep up with the discipline. We got a bell to put on my lil girl when I first got her. She is 7# now but as a puppy shE was tiny! Bell helped a lot! Also a bright t shirt!! I also enrolled her in obedience school asap! She was 2 nd smallest dog but the only one to get a time out in first class for not behaving ! Lol. Does great once she knew I am the bOSS!!
