That is absolutely not true. Some dogs are mean biters from the time they are puppies. Mine were always treated well. I have had at least 2 that fit this category. One was a West Highland White Terrier and the other was a Jack Russel. The Westie ran off and was killed by a cow that he attacked in the pasture and the Jack lived to be 14 when his biting got so bad I put him down. (Can't imagine how I put up with him so long). They were both small dogs so I could control them most of the time. If either had been pitt bulls someone would be dead.
Dogs are only a reflection of their owners.
One doesn’t “Control” dogs. One allows the dog to be who it was meant to be.
Not sure if I like your attitude about critters in your life.
It seems you want more than the critters can give. Don’t be such a perfectionist!
