Owned and purportedly “trained” dogs that bite so often are abused.
A viscious dog is a mirror of its owner and become viscious either through neglect, abuse, starvation, etc.
I don’t care about some white-house dog. It’s an animal, not a human. And I do believe people are charged with proper care of their pets and livestock. Creating a viscious animal [none are “born” that way] does give insight into the owner, however. And a dog abuser is the lowest scum there is.
I’d bet biden gives the dog a kick every so often to satisfy his violence lust, so it fears people and bites at any similar movement.
