We have an almost 3yo male Pyrenees and an 11 week old Bernese. Our Pyr isn't much on playing with other dogs, though will be tolerant for the most part. At the dog park he mostly ignores all the dogs and runs around on his own. He will growl at them, and if a smaller dog is jumping around him or trying to sniff him, he will sometimes turn very quickly but has never snapped. Just growled and run off. We had a Berner pup who was sick and passed away but they got along great. She didn't act like a silly puppy and the only time they played was if he initiated it and it never lasted long. If both were at the park together he would be protective of her and play some but usually still stayed on his own. With the new pup, our Pyr tolerates but not for long. We have had the pup for two weeks now and is also a male. Our Pyr will growl if the pup is whining a lot, and growl and show teeth and has also snapped and nipped at him when he tries to play and bug him. Should I be worried this will only get worse, or in time should things get better? Was getting a puppy with him a bad idea? Any advice is welcomed!
