Another spotty girl, white blaze and white spot on the chin. There is a puppy pic and more recent ones. She’s 13 months now. From a show line, both parents are champions, and many champions in the pedigree.
Her markings were there from birth. when did your dog develop them?
The gene for parti color is in the poodle gene pool, and crops up now and then. Breeders used to cull them, maybe some still do. I would let the breeder know, but it doesn’t mean she’s not purebred. Unless you’re going to show or breed her, it’s not a worry.
Love to see other pics, then we can also comment better based on conformation.
