My older dog bites my new puppy?

My seven month old min pin was recently just introduced to my two and a half month old shih tzu. They're both male.





My min pin acts very aggressively towards the shih tzu, he takes him by the neck and drags him, he bites him, he pounces at him (all of which could be play-fighting, I'm not sure) but it all looks very aggressive. The shih tzu never squeals or anything, if anything- when he gets extremely pissed off.. he chases after the min pin and barks at him.





I'm not sure if I should stop this behavior from my min pin. He looks as though he's overdoing it and it looks as though it could hurt the shih tzu.





I think they're both fighting for dominance. The little shih tzu often times attempts to hop on the min pins back and "hump" him.





...


What do I do?



As long as they are not physically hurting one another or drawing blood I would say just watch them and let them work it out. If you try to interfere it will just make it worse. So often dogs that start out like this end up after a short while being best friends.




dont return the dog, just limit that kind of play. you have to train in order to get good dispositions, spend time training




nothing to worry about. It's just dog life. he wont get hurt.. Whatever you do DONT RETURN THE DOGS. ... NOT EVEN ONE OF THEM I WORK AT AN ANIMAL SHELTER AND ITS SO SAD WHEN ANIMALS GET RETURNED.




you're right to think that they are fighting over who wil be the dominant dog and over time this will stop.




this is normall


do nothing


if u give them the same amount of atention this should stop
