Probably. If your dog is [prone to doing that, then adding a safety strap from the harness to a properly fitted martingale collar would be a good idea. That's what I've done with my pittie when we tracked.I just now thought about this but I wonder if dogs can easily slip out of the ezydog and the Julius harness. I just really like this style harness tho. I like having the handle I Need to use it. But if my dog panics and backs up trying to get out of it will he be able too?
