Can I keep my Yorkshires coat like this? (Pictures Included)?

as far as i know, having the long show coat gives you a better chance at winning a contest, but the puppy cut (short cut) is of coarse the most convenient. as for the cut you want.... It really depends what you want your dog to be more of. A show dog, or a pet. The one you want is adorable, and i wish you the best of luck. (Im almost sure they require a longer coat in show dogs, though!)
