The only reason that a dog will FORCEFULLY flip another dog over on its back is to kill the animal.you read it on the internet so it must be true?
ABSOLUTE BULLSHIT that activity is extremely common in packs and is just a place holder. Why the fuck do you think dogs like their belly rubbed? Because it itches? No they are submitting to you. It is submission/reminder behavior, not killing behavior. Dogs that want to kill hamstring before going for the throat.
Agree on the neutering bit
