You have a great memory! We generally just use a gentle lead and a flat collar, but he pants so heavily by the time we leave the park that we don't use the gentle lead. He pulls a lot when we leave and I'm very worried about injuring his neck. I see a lot of other dog owners with simple harnesses so I thought maybe we should go back to using harnesses, but the straps are a concern during his wrestling sessions.Well in all honesty I like neither dog parks nor harnesses. But as I recall you don't have a private fenced space which is what takes you to the dog park. I would recommend a martingale collar or a more closely fitted flat buckle collar over a harness. You don't want there to be too many straps that another dog could get tangled in.
It was a flat collar. He was wrestling with another dog and it slipped off. I think it was because I forgot to tighten it after grooming him.How did your dog slip out of his collar? What kind of collar was it? Was it too loose? I can’t imagine my minipoo slipping out of her flat buckle collar.
I'll pick up a martingale collar tomorrow, and hold off on the harness for now.Since a martingale is a limited slip collar it is much much harder for a dog to hurt himself. I wish you didn't need the dog park since I suspect the pulling could be trained away more easily if you didn't use it.
