Hello ST In BG,

In understanding some canine behavior, why are some pit bulls so dangerous? Is it the breeding, training or just their inherent nature?
Would these dogs be mostly unpredictable breeds?

Why would a spayed female dog hump another female/male dog?

The vets say it is sometimes exerting dominance over another, or playing.

I have seen male dogs hump cats and people's legs, arms or whatever. Why is this?

Just wondering.
