Behavior of our new male Yorkie Puppy is very aggressive. Is that normal?
 

We have another yorkie female that we purchased at 4 months and she was always mellow and timid. However with the new male Yorkie we just purchased at 8 weeks is completely opposite from her. We've never had a puppy before so we're not sure if the aggressive behavior is normal. He is really aggressive toward the female not to hurt but I'm afraid they will hurt each other at times. What could I do about this or is this the normal for a male yorkie puppy?

Aggression is not a characteristic of male Yorkies in general. What kind of behavior are you seeing that concerns you?

Yorkie puppies in general can be feisty. Puppy litters often play rough with each other and learn from their moms and littermates when rough is too rough. Your boy is very young at 8 weeks and still testing boundaries.

There are also differences among pups/adult Yorkies. My older boy has always been more polite toward other dogs, whereas my younger boy likes to play rough. He is a little sweetie pie, but a bulldozer when playing with his thankfully patient older brother.

When you see him getting rough, redirect his attention. I always break up rough play with a correction and then redirect to performing a few tricks for treats, or a short game of fetch.

Make sure your girl has a place to escape the puppy when she wants. Work on trick/obedience training with your puppy. Never too early to start the training. Separate them when you can supervise. We kept our boys in the same room, but put the younger in an xpen. We had 2 xpens hooked together so that he had more room. Or you can use a babygate to separate if you have a suitable area.

He's just really energetic and constantly pouncing at her and biting at her lol. I guess maybe that is what puppies do. My female is 16 months old and for the most part is fine with it but at times she will rough house back with him lol. I just want them to bond together and make a good pair. The pup wants to be around her constantly.

That sounds like typical puppy behavior. Definitely supervise and encourage him "no bite" and direct toward more constructive play. I still have to tell my boys to "settle down." Being stuck indoors because of weather, they have their moments of wrestlemania.

It will get easier when you can start walking them together too.

Things should come together for your pair as the puppy matures. :)

That makes me feel better because I really want them to get along. He is polar opposite of our female though lol.

You see the behavior that you see in your little boy because the breeder separated this baby about 4-6 weeks too early from momma. Your little girl was with her momma and she was taught by her momma, the necessary things a momma teaches her pups so they are well rounded, well mannered, and they develop into balanced, stabilized adults. Your little male has not been taught how to mature into a responsible, well rounded, well mannered little man.....this is now your responsibility! He is doing everything a baby does, but he has no momma to teach him how far he will be allowed to go. That is a delicate balancing ritual, so that baby is not overly aggressive, nor is baby "submissive and cowardly". One of my greatest pleasures, is watching/studying my mommas actually teach their little ones how to behave...how to react, how to be assertive, but not vicious....how to be respectful of other dogs.....hundreds of lessons and behaviors momma teaches her babies....and that all happens from 6 weeks through 14 weeks. It is really so fascinating to watch how Mother Nature instinctively motivates mommas to teach and correct and love their babies, in order to make them well rounded, emotionally stable babies that grow into great adults. It is one of the saddest things in my mind, when these babies are pulled way too early from their mommas, by people that do not understand WHY babies should remain with mommas as long as reputable breeders leave them with their mommas...they miss out on so much. Our mommas will tell us very plainly and clearly, when they are finished with their job, and left to nurture as it was meant to be, her babies are easily 12-14 weeks old....I have one momma who adores her babies and will stay with them until I let them go to their new homes, even if it is 4-5 months old....she tends to them, and checks on them, and supervises them as they play and interact with the other dogs.........it is stunning to watch!

Sounds like normal puppy behavior to me.

Also, due to the fact this pup was taken from its Momma way too early - you will likely have more challenges with this little one - so you'll have to prepare yourself for the situation. His Momma isn't around to teach him boundaries - so that's up to you and your other kiddo.
