My dog had a litter of puppies 6 weeks ago, one of them, his name is Prince, rolled in urine today so I gave him a bath. He is nice and clean and he was happy until I tried to put him back in with the other puppies. There is a female puppy, her name is Scruffy. Once I put him in, the other puppies were alright with him, nice and happy, but Scruffy was very aggressive. Scruffy has hurt him before in the past, but they were playing and it turned into something more aggressive. This time, they were not playing. Scruffy went up to him and latched onto his face. I had to stick my fingers into her mouth to pry her jaw off him, which resulted in me getting cuts on my fingers. I scolded her so that she knew what she did was wrong, and then I waited an hour and tried to introduce him back in again, she did it again, but this time she hurt his face. He has a small cut above his eye, it isn't bleeding and I cleaned it. Is Scruffy being aggressive because of the way Prince smells now? Should I wait a day or two before putting Prince back in with them? I'm not sure what to do, please help as soon as possible, it would be much appreciated!
