My puppy is developing black spots on her back with black hair is this serious or natural?

Its a jack russell terrier that had an all white coat on her back but has always had spotted skin, pink and black/brown. The black spots have been getting a lot more noticeable when her hair is dry and there are now black/gray hair coming out from them.My puppy is developing black spots on her back with black hair is this serious or natural?
Perfectly normal. the spots on the skin is pigmentation(like freckles) which becomes darken over time like the way their noses turn from pink to black with age. The coat hair is her adult coat %26amp; actual coloring compared to her puppy coat/color.My puppy is developing black spots on her back with black hair is this serious or natural?
This is completely normal. :)





You say ';puppy'; so I am assuming it is still a developing pup, nowhere near full grown yet. Pups sometimes continue to get new markings until they are fully grown, and things like black spots can occur. It is natural for the skin to be dark and the darker hair to grow out of it. :)
This could be a result of her aging and become a more mature dog. Sorry I'm not that literate on dog skin diseases. I would highly recommend you see a vetenarian (I don't know if examining costs money). Best of wishes to you and your dog.
PERFECTLY NORMAL! if a dog is a solid color is is normal to see them have spots develop if the skin is spotted... everything is ok. good luck and enjoy your pup.
its normal if the hair and skin is healthy. if its dried, scaled, sores..so on. that i would seek professional help. if your truly worried and stressed, call the breeder or vet
that's nothing to worry about animals fur changes as they get older my dogs coat did that too and so did my cats....
