We have four dogs........a bassett Bailey who is 6 and about 35 lbs (very small for a bassett, she has chrons disease) a 12 yo min pin/ig mix who is about 20 lbs, Preston - four yo yorkie 16 1/2 lbs and Paisley a 6 lb yorkie. When we got Pais I was VERY nervous. We brought her home at 1 lb, and she seemed so LITTLE that I was scared to death! She is the ornery one of our pack! She did get hurt once recently when they were all chasing a squirel and got barrel rolled.
. Most of the time they are all GREAT together and she holds her own very well, but now I make sure she is out of the way when the chase is on for a bunny, bird or squirel. She sure doesn't get out of the way on her own though!
