On Saturday Feb. 20th, we took our puppy Romeo to one of our regular spots, Tecumseh Dog Park. We had only just started our walk when a Doberman ran up to Romeo from behind, snarling and biting at his back. As we were right there, we were able to grab Romeo and block the Doberman, and removed Romeo to a safe distance. The Doberman dropped back a few steps on the path, and moments later we heard the same snarling and racket as the Doberman attacked another dog. This was not playing. The Doberman was snarling and clearly attacking. There was a bit of a melee of people behind us so we didn't see exactly how it was broken up, but we were quite shaken and started to walk quickly to get away from the group. As I collected my thoughts, I told my husband I was going to talk to the woman who owned the Doberman as we felt very unsafe. I was hoping she would leash her dog, and said to her, Ma'am, I don't think your dog should be in here , she got belligerent and strode right up behind us with her 2 dogs. As she was denying the attack, my husband spoke up too, as is all evident on the video I took (thank goodness I had my cell with me as it was a gorgeous day and I wanted to film the dogs romping in the spring sunshine), and she began cuss and overtake us with her 2 dogs on the path. As the argument went on, her Doberman again attacked Romeo, again, caught on camera. The woman continued ranting and raving and eventually moved off putting distance between us. We saw her dog being unruly and aggressive across the park and in the short time we remained there, she leashed and unleashed him a few times. Romeo was quite badly shaken and stayed by us the most of the remaining time we were there, only venturing to play with one other dog before we left. We saw the Doberman attack yet one other dog before she left and we left, so the attack on Romeo was not an isolated incident. I don't know about the Tecumseh Park, but at Optimist Memorial Dog Park where we often go, there are clear rules posted that should a dog owner request another dog owner to leash or remove their dog, that request should be fulfilled. It's going to be a while before we are comfortable taking Romeo back to Tecumseh Dog Park. Just a heads up to other dog owners.
