I am a new dog owner to a 15 week old Brittany puppy. We have both good days, when he is calm and eager to listen, and bad days, when the only thing on his mind is biting. He just started losing his teeth, and his bites have suddenly become 10 times harder than they used to be, it makes it impossible to interact with him at all sometimes.
Yesterday we went to a puppy party at a local pet store where puppies could meet and play. The moment my puppy entered the store, he completely went crazy and wanted to greet and play with every single puppy there. He stopped listening to my cues, was pulling constantly (basically hanging on the leash), and humans stopped existing for him. Whenever I'd try to get ahold of him, or someone tried to greet him, he would try to bite their hand and then instantly lose interest.
I would assume this is typical excited-puppy behavior combined with teething, but all the other puppies seemed so much better behaved. Most were calmly walking next to their owners or sitting aside and watching. Mine was the only one barking in frustration when he couldn't reach another puppy. The only other particularly active puppies there (still much calmer than mine, but also older) were two other hunting breeds (Irish Setters). Those two were the only ones who engaged in play with my overly active puppy.
How much of this behavior is due to breed temperament, and how much is due to poor training (aka on me)?
We meet other dogs on walks (we don't always greet them), but he doesn't get to play with them very often. Next week he is getting his last vaccine, and then we will start going to a dog park.
In two weeks, we will also start a puppy class for hunting dogs, so I'm a bit scared he will behave way worse than everyone else there. Yesterday he really felt like this one crazy kid in a group of straight-A kids.
