Yes. Freckles are common in certain breeds of dog and often become more prominent with age or after a dose of summer sun. Often referred to as Ticking, freckles are caused by a series of dominant genes that effect the melanin production of your doggie’s eyes, coat, and skin.

A Cattle Dog’s roan markings, as well as a Dalmatian’s spots, though technically different from freckles, are also controlled by this T-Series gene.

If you are looking to unravel the mix of your mutt, it may be useful to know that ticking is most often found in Dalmatians, Cattle Dogs, English Setters, as well as many spaniels and hounds. Australian Shepherds, Border Collies, and Corgis are some of the herding breeds that also carry ticking.

Final Note: though a dappled doggie can be adorable, if your dog's skin seems itchy or irritated, it can be a sign of something more serious. Some basic information on canine skin problems can be found on the ASPCA website, but always consult your veterinarian if you have any concerns.
