My wife had our son on the floor the other day playing with him and doing tummy time. Tyson our dobe was just laying beside her and my son chillin out. My wife got up to get a glass of water and came back to pick up Colin and Tyson snarled at her showing his teeth. He didn't growl or anything just showed his teeth and didn't snap at her. Tyson has always been protective of Colin since he was born and during the day sleeps by Colin's crib when he's in there. Tyson has only done this one time and hasn't done it since then. Could this potentially lead to an issue or do you think he might have just been spooked?
