I have three lab puppies. Three months old, all males. One of them started viscously attacking his brother for no reason! What do I do????
This might all depend on your definition of "viscous". Puppies play pretty darn rough, it is what they do.
It's impossible to say what's going on without seeing it. It could be just play - puppies and dogs can sound and look awfully scary when they're playing. But it could also be that he is telling his brother off; at the rescue I volunteer at, there is a litter of nine puppies about the same age as yours, and there is quite often noisy squabbling between them all. It doesn't mean anything serious, it's just them setting boundaries as their personalities develop. At this age, it's very unlikely to be true aggression. However, I would urge you to do some reading around littermate syndrome. I have litter mates myself (a boy and a girl, now three years of age) and I was very careful with their upbringing to ensure they had a huge amount of individual time so as not to end up either overly dependent on one another, or getting serious aggression issues with one another. It's hard work; far harder than having a single puppy, and doing it with three? Wow! What made you do that, are you nuts?
