Their yard is not huge she lets them out when they need to go on a chain then they come back in. She says there is plenty of room for her animals. My main concern is the pit bull gonna be mean? I admit she is a good trainer! And her dogs are well behaved but i dont know.. The pit is only 3 months, she got it for christmas from her husband. But dont they need more room? Do you feel like she has to many animals? I wanna say something to her but dont wanna ruin our friendship...
Update: Yeah I never said she was a bad pet owner, they have all their shots they get walked in summer time lol she is not a big fan of cold. For the ten years ive known her she thinks 70 is chilly! But anyways the landlord wont allow her to have a fenced in yard sadly :[, my husband offered to build one for her.

I was just wondering about the living space would be to small just wanted opions, i could never own that many dogs in a trailer. And the person who said there are no such things as minature labs she has papers stating its a pure breed but never got any bigger then maybe 30 lbs? hes only as tall as like a boston terrier little bit taller. Not the minature boston terriers but the taller ones LOL.
