Coco and I went to puppy class. He is really such a good little guy, but he has some things to work on. We didn't have a good night! Another dog bit Coco's tail (and nipped my behind) during recess!! I knew the other dog was being aggressive, so I picked Coco up to walk around. He jumped up to grab Coco's tail and pulled his hair. Coco sat under my chair the remainder of class. Hope that dog doesn't come next week...we will leave if he does!!
