A dog bite wound almost always needs a vet within 24 hours, even when the skin puncture looks small: canine teeth crush and shear tissue underneath, and bacteria from the biter's mouth are pushed deep, so up to 20% of untreated bite wounds become infected or abscess within 3–5 days. Rinse the wound with saline, cover it with a clean cloth, keep your dog calm, and go - do not wait to see if it “settles down.”
Persistent bad breath, brown or yellow tartar along the gum line, red or bleeding gums, and dropping food while eating are the classic signs of canine periodontal disease. By age three, over 80% of dogs already have stage 1 or 2 disease, and untreated dental infection is linked to heart, kidney, and liver damage - so a photo check every month and a professional cleaning under anaesthetic every 12–18 months is the standard of care.
Persistent itching in a dog is most often driven by flea allergy dermatitis, environmental allergies (atopic dermatitis), food allergy, or a secondary yeast or bacterial skin infection. Rule out fleas first - a single bite can trigger weeks of itch in a sensitised dog - and book a vet if the itch stops your dog sleeping, if the skin is broken or smelly, or if it has lasted more than two weeks.
Redness, cloudy discharge, squinting, or a swollen eyelid in a dog most commonly signals conjunctivitis, a corneal scratch, dry eye, or an allergic flare - all of which need a same-week vet visit. If your dog is holding the eye shut, pawing at it, or the pupil looks cloudy or blue-tinted, treat it as urgent and go today: corneal ulcers can perforate within 24–48 hours.
Patchy hair loss in dogs is most often driven by flea allergy dermatitis, environmental allergies (atopy), demodectic or sarcoptic mange, or a hormonal condition like hypothyroidism or Cushing's disease. If the hair loss is symmetric on both sides of the body, is spreading fast, or comes with thickened dark skin and a musty smell, book a vet within the week for skin scrapes and bloodwork.
