I was wondering if anyone had any experience with dog vest. This will be my Lab pup's first year out and I was going to get him a vest. I've seen a couple different kinds and was wondering if anyone had any recommendations. Should I go for velcro or a zipper? Also I heard that they make one with a handle on the back in case you need to help them in to the boat but I haven't been able to find that one. If anyone has any expertise in this I'd appreciate it.
