Poor Panda plays with Roxie and the hair tie vanishes. What do you do? Well some dogs LOVE a target and a hair tie can be a target but you can correct and stop the behavior. Some dogs love to pull tails or chew on necks. All of this is correctable and if you had a show dog and you didn't want to wait it would become a mission to correct and refocus.
But if you have a pet - does it matter? Well we have show dogs and I would rather my dogs have fun and wait till it grows back then to ruin the fun so early in their lives. By taking the play out of them you will have a dog that rarely plays.
So what do you do if you care about their play and want to keep their coat? You are asking me with 3 dogs with chopped hair from play? Well, I am now getting serious in correction and its working. I am showing them you can play without chewing but when we have a visitor its a new lesson always and hey I still like to see my dogs play above any desire for a long coat.
It's only a bad haircut folks but a happy dog is a happy dog no matter what it looks like. :-)
