Just call me stupid.......

I'm sure you're getting great advice here but wanted to add my German Shepherd was THE mouthiest pup in the world (and mostly only to me) when I first got him. I've got scars to prove it Puppy teeth, ouch! I had that same fear for a split second, "this dog is gonna be hell on paws!" but they do truly grow out of it. T-Bone is 8 months now and he went from routinely drawing my blood to not mouthing. I found giving him a toy was definitely the way to go. I tried all the different ignore, hold his muzzle, etc. I taught him "Easy" where I hold a treat very close to his nose, and play with his ears and toes. When he went fo mouth me I'd say AH, AH, eeeasy. When he stopped and focused on the treat, he got it. He finally got to where he didn't even look at what I was doing, and if he starts stressing at the vet or something, a simple "Easy" tells him how to act. T-Bone bit the vet when he was little, and since has learned never to mouth people in anger (lol) there IS hope, don't give up. Exerccise, keep monster's mouth full, and socialize. At this young age it' time to socialize her with kids/moving objects. a solid "sit, focus" is good. After the movement is gone reward and throw a ball like crazy! I'm not a trainer but this worked for my mouthy pup
