Hi everyone! My name is Kevin and I've had my pit bull zeke for four years now. I also have a chow chow. My pit is a male blue grey brindle. My chow is female. My pit is very energetic and always playful. He's great with my kids and pretty good when people come to the house with the exception of when they first walk in. He wants to b petted. He's sometimes over hyper and jumps on em, but when they r in and settled he's fine. He is very submissive to my chow. She's pretty much the boss even though he's double her size and weight. He's prob around 80 to 90 pounds and when he gets outta line she puts him in place. Never had a fight between them, just playfulness. He of course has way more energy and over does it but she will let him know when it's time to quit and he usually does but sometimes I have to separate him from her cuz he's persistant and he's a brute and can be a bully. Lol. My chow is now 13 and just wants to chill and not have his big *butt always in her grill wanting to play. Now to what I really need advice on! My girl friend bought a puppy. A pit and korso mix. Female. She brought her over a few times to introduce the two. The first time. I held the puppy and let zeke come up on me. He tried taking her paw in his mouth and pulling her. Nothing hard though and right away I pushed him down. The second time my girlfriend help the puppy and he jumped at her and went to nip the puppy but got my girls fingers. It wasn't hard. Since then we would just put her in her crate while zeke is out. And he paws at the cage. Occasional licking through cage. He does show signs of wanting to play. Tail always wagging. Chest to floor. *Butt up. But he sometimes will pounce at the cage with his big self and scare her. And sometimes will stiffing up. Hes so excited his body shakes. Lol. When zoey is here zeke does not leave her alone. It's been three days and I still do t know if I can trust him to b gentle and k ow his strength with zoey. Any advice will b great. Please!!! I never had this problem with my chow. She don't *care about the new puppy.
