My 11 month old male boxer, Rough & Tough, has been going to the dog park for about 6 months now and day camp once a week for the same. For the past couple of months when we go to the dog park he will be through the gate and have another, smaller dog pinned to the ground as he snarls. I have asked the day camp counselors about his behavior and they say he plays a little rough but he is only playing, he has never snarled there. At the park when he gets like this I pull him off the other dog and do a "mommy hold" place him on his side and grab the scruf of his neck and hold him there until he is calm. He will then get up and do it again. Does anyone have this problem or any experience with it ??????? He is a very loving and playful boy at home with me but I would love to have him keep going to the bark park.
