So our puppy is now 8 months old. I'm thinking he's a bit of an alpha dog, and he is just at the age where he is constantly challenging us.
He's a bit of a food monster, and he constantly tries to take our food from the table. When he jumps up I make a noise to get his attention, and grab him by the scruff, and just put him on the ground. Not violent mind you, but just enough to get his front paws off the table. He'll keep trying though, and the more I disclipine I give him, he starts to get frustrated. This usually escalates to him letting out a bark and a bit of a growl, and then sometimes he'll bite me. Not hard by any means, just a little nibble, and he cries when he does it. I'm guessing this is out of frustration.
I do all the normal behaviors that make it clear to him that he's not the alpha dog, we make him wait to eat, and even go as far to putting my face in his bowl before he eats. I also do the same thing when I fill his kong, with peanut butter. I pretend to eat some of it first, then I give it to him.
So anyways, I'm guessing this is just a result of his alpha tendencies (the breeder told us he was the 'gregarious' one of the litter) and his age. But I would feel a little better if anyone has had similar experiences or had some more advice on how to handle him.
