My 2-month-old long-hair golden kitten has black spots on its body and nose; is it ringworm and what medicine?
Black spots can come from genes, pigmentation, folliculitis, or melanoma. Genetic spots show no other abnormality. Melanoma shows hard black growths. If these appear, get a vet check for metastasis elsewhere.
My dog’s tail base turned black; the skin is white, no scabs or ringworm seen.
A black tail base may be normal melanin from age or sun, with no other symptoms needed. Past skin disease, harsh shampoo causing chronic dermatitis, or mites/hormones can also do it; see a vet if uncertain.
What causes black spots on my Chihuahua’s belly?
Black spots on a Chihuahua's belly may be normal melanin deposits or signs of parasites, fungus, or other disease. If accompanied by hair loss, itch, or redness, it is likely a skin condition needing veterinary diagnosis; alone, it is probably harmless pigmentation.
Why do dogs have an eye line (eye rim pigment)?
Eye line is genetic, usually black. Besides beauty, protects the eyes—blocks sun and sand, prevents injury. Desert/high-altitude dogs have denser lines against UV/sand. Also reduces deposit of eye discharge and dirt.
My cat was fine yesterday, but today its back has turned black in patches and the fur is darkening. What’s wrong?
Because the fur changed suddenly, first check whether the darkening is from dirt, paint, dye or ink. Try wiping with water or pet wipes; if it smears and comes off it is just dirty and a bath will do. If it won't come off, part the fur to inspect the skin for redness, itching, rash or scabs, which suggests skin disease or follicle problems needing a vet.
Hair loss and blackening under the neck
Hair loss and blackening under the neck may be fungal infection or a metabolic issue. With no dandruff or scratching, try supplements and observe; if from melanin deposition, add vitamins and cod-liver oil. Pigment buildup only affects looks, but see a vet if other skin changes appear.
The fur around my dog’s eyes has a black ring that has lasted a while—what is it?
Causes: 1) tear stains—blocked tear ducts/oily diet/excess tears; iron ions oxidize to brown pigment. 2) bacterial/fungal/mite skin infection causing black discharge. 3) genetics—natural melanin, harmless. 4) external factors like chemicals/dyes. No exam, so see a vet; feed light, clean eye discharge, don't self-medicate.
Why does my dog have many black spots on its skin?
Black spots on a dog's skin may be from melanin deposition. Frequent sun exposure or UV radiation can cause local black spots. In older dogs, age-related pigmentation is normal and not a concern.
A Teddy has blackened, weeping, flaky skin — is it contagious and how should it be treated? Will it spread to my other two dogs?
Widespread black, thickened, rough, flaky skin with hair loss suggests black acanthosis, a syndrome from many causes such as demodex, seborrhea, endocrine disorder, or vitamin A deficiency. Contagion cannot be ruled out, so strictly isolate and disinfect the dog. A stray with these signs often has a serious condition needing veterinary diagnosis.
My Cat’s Ear Started Peeling and Losing Fur Around July 1; the Skin and Fur Came Off Together When Scratched, a Wood’s Lamp Showed a Glow, and I Applied Compound Ketoconazole Ointment After Cleaning with Saline. Two Small Spots Healed, but a Larger One Turned Black and Scabbed. Thank You.
Based on your description, the darkening of a cat's ear skin after a ringworm infection usually has two causes: severe fungal damage to the skin base causing pigmentation, or the combined effect of long-term medication and antifungal-drug hormones.
