Ok so today was Beemer's second time going to the dog park. The first time we went he had a blast! There were only 2 dogs there and he ran and ran and just loved it. This time though there were about 10 or so dogs there and I sat on the picnic table and watched him run in the sand by himself and then he just came back to me and sat under the picnic table. When other dogs would try and come up to him he would simply run out from under the table and they would chase him and he would jun back to me. I would get up and he would follow me around the whole park instead of playing. I mean I am glad he is so intuned with me and wanting to be by my side, but I want him to play and get socialized with other dogs. Any tips, or advice, or comments?
