She weighs 36 lbs. She really hasn't been around children. The only issue I have had is towards one of my other dogs. I would have to say that she needs a one dog home. I am not sure if she is Pit Bull mix but her build looks like it. She is part Beagle. I walk her 30 minutes everyday and she loves it. I take her to Pet Supplies to get bath and nails trimmed. She loves that too. She doesn't show aggression in the store, only toward my one dog.
