Cheryl,
That is the dog park we go too. My fiance has a beagle who just walks around, but Dugan usually gets into the hard core playing. He is the same way with the pouncing. The only problem with that park is that all of the dogs are trying to be top dog. My Dugan always seems to get humped by the other big dogs and he gets tired of it. I know that they are trying to establish dominance, but other dogs join in and it always seems to get a little out of control with the growling. So far he hasn't gotten in any fights, but I would hate for it to happen. Therefore we've been limiting our time there. He never starts anything, it's usually others then he antagonizes by barking. Well I'm done rambling. Let me know anytime you want to get together. We live so close.
