Yesterday, my toddler was playing in the yard with our Dobe, Duke. He was definitely JUST playing with her. They are very used to eachother, they used to fall asleep on the couch together. He was jumping around and licking her face then suddenly, he bit her arm. It wasn't hard. She didn't cry and it didn't leave a mark. But just about her entire arm was in his mouth and my heart sank to the ground! I've never seen him do that before, and he is still a very goofy puppy and they were just playing, but should I be concerned? I'm almost scared to let them play together right now. He's taller than her and weighs almost three times as she does. So, I'm just little anxious about it.
