I have an 8 month old pit bull and I just got a new ~2 month old bull mastiff/husky puppy yesterday (both females). There were no problems between them when we brought her home except that our pit is very hyper/playful and too large and sometimes too rough when playing with our puppy. When they do play, our pit is constantly on top of the puppy (almost mounting her, but not as if she was trying to hump her), pawing at her, pushing her and rolling her around. I don't think she is hurting the puppy because the puppy only growls and only sometimes whines/screams. When they're not playing, our pit is constantly in our puppies face, trying to step in front of her or cut her off as she walks. When our puppy is sleeping, our pit paws at her and whines. At first I assumed she just really wanted to play or was showing she's the dominant of the house, but it is really getting out of hand. When she's too rough I squirt her with water from a spray bottle and at first it made her stop, but now she'll run from the water then go straight back to our puppy and continue doing what she was before. This is when I put her in her kennel for a little while as punishment, but as soon as I let her out, the bad behavior starts up again.
I really don't know what to do, or why she's acting like this and I can't find any direct answers or any answers that pertain to our situation. Does anyone know why she could be doing this?
