i have a 3 year old brittany/beagle/setter mix. he is an indoor dog, fed a high grade diet with some table scraps, and is up to date on vaccinations. he has an odd coloring for his breed mix, mostly red and black. i have noticed lately he is getting very grey around his muzzle and have wondered about it for sometime, but brushed it off as he has not showed any other signs of premature aging, but tonight i noticed one of his whiskers above his eyes was white as well. i was just curious if i should be concerned enough by this to make a specific appt with his vet right away or if it is something i should just wait to mention at his regular check up in a few months. also im not sure if it would be a cause or effect to this, but he is inbred, "bad inbred" as my husband would say, as the sire was the son of the dam he was born of.
i have included a picture, while blurry shows the amount of white around his muzzle. he has always had some white there but it has been increasing greatly in the past year.
