I have a two year old male lab and a 4 month old female lab. I guess let me start from the beginning. The two year old male has had some anger issues with me during the first year possession with food etc. But I now have this corrected and have not had issues with him in a long time. I got the female at 8 weeks old introduced them in a neutral location and everything was fine. I brought them home and he wacked her on the head. This was probably my fault for introducing them to fast etc. Second time was a month ago when the puppy was by him sleeping, not sure if she jumped on him or what but he bit her again requiring a few staples on the face. Third time was last night, the male was drinking some water and she ran past him and he bit her again requiring a few more stitches. Is this stuff normal? These two are fine most of the time usually playing together running around with no problems. He never has really laid into her but just gave her a quick whack.
Is there something I can do? He just worries me if this keeps going on and hurting the other dog and also when we do have kids is he going to be a problem.
Any suggestions or past experiences would be great.
