Well, I wouldn’t put it that way, myself, but a big part of the problem (or “the” problem) is when dogs are allowed to maintain “alpha” status in the pack. The owner is the alpha. Or they better be.
I would never leave an infant or small child alone with a dog, period- no matter the history, how much I might trust them, or how much they love the kids.
I don’t leave my dogs home alone to fend for themselves if there were a fire or a break-in, either- so maybe I’m just weird.
I am not part of the pack. I am their master, period. If I was part of the pack then it would acceptable for a member of the pack to challenge me and that ain’t happening.
One of the dogs is alpha in the pack. In my home it is the pit mix. It used to be one of the smaller males but the pit got big and the torch was passed.
Only an idiot would leave a small child or baby alone with a dog so I am not going to address that issue.
I can’t take all six of my dogs to work or to the gun range so they are left to fend for themselves. They can stay inside if the weather is bad or go out the doggie door if one of them starts a fire.
