There is almost always a trigger to any aggressive act. The only time there may *not* be a trigger is when a dog is seriously mentally unstable or otherwise ill. Even with "hair-trigger" dogs (i.e. dogs that seemingly react to nothing or very slight changes), there are series of triggers that build up to the act of aggression. For example, a mere change in the environment can easily set off a reactive dog. You may not notice it, but the trigger is there. The hard part is then identifying the triggers and reading your dog's body language correctly.

It's actually a pretty thrilling puzzle. My first suggestion would be to make a list of all the times your Pap attacked your Tzu. Make note of as many details as possible. Be sure to include where they were, what they were doing, how close they were to each other, and what YOU did or did not do. After you do this for a few attacks, you'll start noticing similarities.mFor some dogs, you'll find a common thread very quickly. For other dogs, it takes a bit of brain-wracking, but we can help you with that So if you're having trouble deciphering what went wrong, just post your list here, and we can help.

Also, stop giving the pig ears. My Peke used to hoard and hide his Greenies. He would then guard his Greenie with his life and that caused many unnecessary scuffles. I didn't see the Greenie because he'd often hide them behind chairs or shelves. That's what sounds like is happening with your dogs, but you should double check with your list just to make sure.
