I have a generally well-behaved miniature schnauzer. I am keeping my friend's schnoodle for a week... in general, the dogs get along well, but my dog is being territorial and jealous. He's going after the schnoodle whenever the schnoodle comes to me for attention. My schnauzer has also tried to attack the schnoodle when the schnoodle barked at my dog (when my dog tried to steal food/toy from the schnoodle). HELP! Am I supposed to let them figure out dominance? I don't want anyone hurt! Any thoughts about this would be appreciated.
