Mouthing another puppy's head?
My GSD, Rocky, is about 7 months old. My neighbor's yellow lab is about 5 months. They are buddies and play regularly.
Every time they get together Rocky spends half the time mouthing the other dogs head! Since Rocky's mouth is so big, he can fit the other dog's entire head in his mouth. He's not hurting the other dog, but the poor puppy ends up covered in Rocky drool and we spend time pulling them apart.
Is this a dominance behavior? Any ideas how to get Rocky to stop? BTW, he only does it to our neighbor's dog. At the dog park, he's totally fine!
