Separate separate separate
as in use a puppy pen a large breed puppy vs an aggressive small breed adult is a long term issue
Absolutely do NOT tolerate any aggression if there is aggression take "it" away.
Separate, use doggy time out, keep all treats toys locked up have plenty for both if you can if it isn't working separate with play yard let them be next to each other but unable to touch each other this is the key when they have to be close but can't be aggressive they get over it and without injury.
Growling at each-other is as unacceptable as biting any aggression is unacceptable. |
