I have an 11 year old lab/border collie female, and a lab mix puppy about 9 months old. We've had him since February and has proven to be quite a handful, but we're trying to use the info I've learned from the Kingdom of Pets and Dog Whisperer. I don't know if it's a problem or not, but when these two play, they sound like they're killing each other. I feel like I'm watching the Animal Planet when these two go at it. The older one has never played like this before with any other dog, even her companion, we had to put down in January.
My concern is how do I know if the puppy is playing or being aggressive. I fear he is actually part pit bull also so I'm quite wary. Are there signs I should be looking for? I take them to the dog park and he plays like this somewhat with other dogs, just not as extreme, and now growling.
