So I took Fredo to the dog park for the first time yesterday..needless to say he could not get out of bed this morning...lol My question is, some of the dogs were being very rough on him, biting his skin and pinning him down and stuff...I was not sure if I should step in or not b/c the other dog moms and dads were doing nothing. Also I did not want to correct anyone else's dog, but some of them had their lips back, showing teeth, snapping the owners did nothing. He seemed to get the hang of it later on but is this kind of play ok? I checked him and no one broke the skin, I was just worried they were picking on my baby. He's still only 5 1/2 months and was the smallest one there even at 43 lbs.
