Noticed a rash on your dog, or wondering what those bald patches on your cat mean? Our AI can help identify common dog skin infections and cat skin problems from a photo. Also try our eye infection photo analysis tool or dog ear photo analysis tool or view pricing plans.
Dermatitis is the most common reason pet owners search "my dog has a rash." It shows up as red, inflamed, itchy skin that may be flaky or scaly. Your dog might scratch constantly, and you may notice hair thinning in the affected area. Allergies, food sensitivities, and contact irritants are the usual culprits. Cats get it too, though they tend to over-groom rather than scratch. Upload a photo to find out what's going on.


Hot spots seem to appear out of nowhere — one moment your dog is fine, the next there's a red, moist, oozing patch that spreads fast. They're incredibly itchy, and your dog will lick or scratch the area obsessively, making it worse. Golden Retrievers, Labradors, and German Shepherds get them most often, especially in warm weather. Quick identification is key, because hot spots can double in size within hours.
Despite the name, ringworm isn't a worm at all — it's a fungal infection. Look for circular patches of hair loss with crusty, scaly edges. It's one of the most common cat skin diseases, especially in kittens and long-haired breeds. The tricky part? Ringworm is highly contagious and can spread to other pets and even to humans. If you spot suspicious round bald patches, upload a photo right away for a quick check.


If your dog is scratching non-stop and losing fur in patches, mange could be the cause. Sarcoptic mange (caused by mites) brings intense itching and crusty skin. Demodectic mange is less itchy but causes patchy hair loss, usually starting around the face and paws. Both types can spread quickly without treatment. A photo can help our AI tell the difference and suggest whether you need an urgent vet visit.
Even a single flea bite can trigger a massive reaction in sensitive pets. You'll see intense itching, redness, and hair loss — especially around the tail base, belly, and inner thighs. It's one of the top reasons behind "my dog has a rash" searches. In cats, flea allergies often show up as tiny scabs scattered across the back (called miliary dermatitis). The irony? You might not even see a flea — it only takes one bite.


Pyoderma means "pus in the skin" — and that's exactly what it looks like. Small red bumps, pus-filled blisters, circular crusts, and areas that smell bad. It's usually a secondary infection that shows up when something else (allergies, mange, or a wound) has weakened the skin's defenses. The good news is it's treatable with antibiotics, but getting the right diagnosis matters. Upload a photo and let our AI take a first look.
