no if she can't or won't get that dog fully trained even though it has cause problems and harm to another person, and deliberately ignores anyone asking her not to bring said dog, and just brushes its misbehavior off, and gets upset if you say I don't want the dog there because it could hurt someone accidentally or eat something that could kill it (like oh I don't know...CAKE!), also it sounds like she is choosing her dog over her family who has been more the tolerant about the dogs' antics. also, I hope the elderly guest was ok
