My dog keeps biting its toes and paw pads—probably itchy. What’s wrong?
From the picture it may have interdigital dermatitis, common between toes or on the paw, usually from prolonged moisture breeding bacteria, and secondary to issues like foreign bodies, trauma, demodex, food allergy or endocrine disease. Treat the underlying cause too: use an Elizabethan collar, clean with saline, disinfect with iodine, apply antibacterial ointment, and keep paws dry.
My cat scratched its ears raw; inside is smelly, dirty and has pus—ear mites or something else?
Pus, tissue growth and odor with scratching suggest secondary bacterial ear infection, often from mixed bacteria, fungi and ear mites. Clean twice daily with an ear cleaner (not cotton swabs), then apply antibacterial drops like Posatex or Epi-Otic, with a loose collar. If it persists, see a vet to avoid inner-ear damage.
What happens when a fish loses its scales?
Fish scales are a protective layer that reduces friction, prevents water loss and blocks pathogens. Once lost, the fish is more vulnerable to bacterial, viral and parasitic infection, which may lead to skin rot and even death if untreated. Disinfect promptly and keep water clean; new scales will grow back if the skin is not infected.
My cat has a black lump on its hind leg
From the photo, the scab on the cat's hind leg is usually from a wound that formed a scab. The broken skin may be from a bite or long-term friction. Bacterial or fungal infection can also cause hard scabs. Gently clean and disinfect the scab without pulling it off to avoid harm; if from infection, use antibiotics or antifungals.
Why does my hamster have a small pus bump around its eye?
From the photo, a small pus bump around a hamster's eye may be from bacterial or fungal infection; take it to the vet for a skin exam to confirm the type and treat accordingly. If a visit isn't convenient, disinfect the area and apply antifungal and antibacterial medication, and use an Elizabethan collar during treatment to prevent scratching. Another possibility is 'heat' (diet-related), needing a lighter diet, saline cleaning, and eye drops.
What is the best way to care for a baby alligator snapping turtle?
Caring for a baby alligator snapping turtle requires attention to the following: 1. It needs a suitable habitat such as a glass tank or plastic tub, with sand or fine gravel at the bottom and clean water. Because they grow fast, adjust the tub size and water depth as they grow. 2. It needs a suitable temperature, ideally 24–30°C, maintained with a heating lamp or heat mat.
My dog’s skin around the mouth is pink, fur is thin, for a while, no scratching; is it a skin disease?
Thin fur and red skin around the mouth may be from unclean diet or secondary pathogen infection. Food and water residue left damp breeds bacteria, mites, and fungus causing redness and allergy. Check for dandruff or ringworm and do a cytology; clean after meals, deworm, and use antibiotics or antifungals. If a vet visit is hard, use a broad-spectrum oral spray and low-allergen food, keep the area dry, and use a collar.
The hard lump or scab on my dog’s hind neck is bleeding
A red hard lump or scab on the hind neck has many causes: a recent injection with poor absorption forming a lump the dog scratched open, or improper injection causing bleeding; or fungal infection or pyoderma. If hair loss appears, stop licking/scratching, get a skin scrape, shave and disinfect, and treat; never let it scratch the wound.
No dandruff but a bit red and swollen
Ringworm usually brings patchy hair loss, redness, itching, and dandruff. From the photo the cat has hair loss and redness; besides ringworm it could be folliculitis or bacterial/parasitic infection. If it worsens, see a vet to confirm and treat.
At first loose stool with a soybean-sized lump on the belly, then bloody loose stool, but the belly lump shrank and nearly vanished
Loose stool with blood usually means gut infection or damage from parasites or a foreign object scraping the gut, but parvovirus, bacterial enteritis, or constipation are also possible. See a vet to find the cause; for parasites, deworm and use gut-lining repair drugs and probiotics.
