[Draco]

Hi guys, it's been awhile! I guess I want to reach out to fellow yorkie owners for any tips for the best way to approach this situation with my roommates dog. He's somewhere between 6-8months and I'm afraid of his bad behavior rubbing off on Draco or just becoming incredibly hard to break. It's getting harder to overlook the dogs behavior. Draco is about 7-8lbs and this dog is about 12-15 and about the size of miniature schnauzer.

The dog looks at Draco like he's a toy, stalking him then pouncing on him and goes straight for his neck or legs. Sometimes Draco engages in playtime but often the dog goes for him when he's just doing his own thing and walking around. Draco will yelp sometimes too. Though I'm good with dog behavior and the dog isn't exactly aggressive or trying to dominate Draco. And Draco doesn't fear him, snarl/growl at him or show any dislike towards the dog. He's a rescue and I wouldn't label the dog aggressive at all, he's actually pretty skittish.
While I don't expect dogs to understand sharing the dog hoards all the toys and goes and takes any toy from him and hides it. He also has destroyed many of Draco toys, and eaten my underwear! He also has nervous/excitement peeing which isn't his fault but adds to my frustration.

I'm just trying to figure out how to approach my roommate. I clearly like to spoil my dog and am obsessed with him and everything he does. I have to admit that there was a puppy charm that was willing to let him get away with a few things, but it's gone now and my roommate doesn't hold her dog on as high a pedestal nor corrects his behavior enough.
