Yes I have a little squealer too. I got him when he was 4 months old because he was soo small. He has always been this way and sometimes it drives me nuts. But we have learned to deal with it the only time he barks is when he needs to go outside so we know the difference. He growls and pretends to be a big dog around my Rottweiler but I think he is just playing because it never escalates and he lifts up his but and wags his tiny docked tail while he's at it. I've tryed everything including a trainer that has came over several times to my home and nothing has worked I just gave up he's over 2 that's just him being him
