I got really upset this morning at the dog park. We have a very well kept privately owned (but open to the public) park by my house. It is normally a great place for the dogs to run a play with friends and for the most part is occupied by good dogs and good, responsible owners. It is not city owned and is not a well known park by the public. We don't seem to get a lot of the troublesome owners and improper "dog park friendly" breeds there....well....Sunday's are the exception I guess...Jazz and I were on our morning walk through the neighborhood and walked by the dog park...My first instinct was to avoid the park on such a busy day (15-20 dogs which is a lot for the size of this place) but since Jazz was jumping up and down and begging me to go inside, I went against my judgement and went inside anyway...big mistake!!!! At first it was okay, the dogs were playing and having a good time, but, then the trouble started. There was a 150+ lb. dog (possibly a Newfoundland..not sure) that would not leave Jazz alone! He would not stop humping her!! The first time it happend I called Jazz and she came running to me. The owner of the dog just laughed at the situation and went back to his latte and conversation. The second time it happened, Jazz was pinned so I had to tell the dog no and had to pull Jazz out from under him....still no response from the owner other than a chuckle. I'd had enough and was afraid this dog was going to hurt Jazz so decided to leave and finish our walk. As i am leashing her the dog sneaks up and mounts her again and used my forearm to push the dog off of Jazz so we could leave. At that point the owner came running at me, screaming "don't hit my dog mother (explicit), what are you doing?!?!" I told him I didn't hit the dog but had to get him off mine before he broke her back. His response was that "thats what dogs do, that's how they play and check each other out"...I explained that humping is not how dogs play and needs to have more control over his dog and that humping is not an acceptable behavior...it is a sign of dominance and can be a sign of aggression when a dog lays or puts his paws on another dog as his was. I also said he needs to put his latte down and pay attention to his dog. He kept trying to pick a fight with me so I left. As I was wallking away I looked back and watched everybody in the park for a minute and it seems that no one was watching their dogs. They were just sipping their coffee, mingling without a care in the world. That is not how you act at a dog park!! I was the only person there that was playing with the dogs, throwing balls and frisbees and interacting with the dogs. In my opinion, the dog park is a place to take the leash off and play with your dog in an open area..it's not a daycare or a singles club!!! Thanks for letting me vent!!!!!!
