I didn't actually put the Vicks on his leash...I let him smell it first on my hands, no effect, so I didn't bother. I thought it was kind of odd, but those are the things the trainer mentioned to stop dogs from chewing/biting things. The problem is that I have to keep him on a leash quite often. He's on one in the house sometimes because I can't have him going after Reggie and Smokey all the time (he's just playing, but they aren't). Lol Anna, I'd love to get him a playmate hehe. I wish Reggie and Smokey would be, but umm..no....He has Lady, but he doesnt' see her all the time.
