Even if you don't have a Dally like Wiley and his phenomenal heart-shaped nose, there's usually not much you need to do beyond basic grooming to keep your Dalmatian's coat in super shape! And while a Dalmatian-styled faux-fur coat is occasionally all the rage — on the silver screen or at a party — the look sits quite nicely at all times on this breed and does so with basically no clipping, cutting, or styling.
Then there is the very rare Long Coat Dalmatian. These long-haired dogs number in the low hundreds worldwide, and if you have one, you know that there is some room to style parts of their coats. At the least, you will need to occasionally trim their leg, ear, tail, and "beard" hair as it gets longer than the rest of the coat, is prone to tangles, and is best styled in a feathered fashion. The beard hair needs only be kept from getting so long as to be unmanageable. While a "beard" trim seems simple and easy, it can just as easily look off-balance if not done properly. Let a groomer do it and show you how until you are ready to do it right.
Finally, never shave a Dalmatian unless it's a medical emergency. This breed tends to not have the problems that most dog breeds have with massive tangles and gnarly mats, and shaving off the coat can quickly cause a lot of serious health concerns. Skin infections, sunburn, and doggy depression are just a few of the many conditions that are sure to occur with a shaved Dally. If you prefer a short, tight coat, have a professional do it so that you don't cut their delicate skin or end up with hot spots.
