Pet symptoms library

    Warning symptoms in dogs and cats: what to do at home, when to call the vet. Triage for 12 common complaints.

    Urgent

    Vomiting in Dogs and Cats

    A single episode of vomiting is common, but repeated vomiting, blood, or accompanying lethargy needs same-day veterinary attention.

    Urgent

    Diarrhoea in Dogs and Cats

    Short-term diarrhoea often resolves on its own, but dehydration develops in puppies and kittens within hours — watch closely.

    Urgent

    Lethargy and Weakness in Pets

    A sudden drop in activity is non-specific but important. Often the first sign of serious illness.

    Monitor

    Limping in Dogs and Cats

    Limping signals pain. Mild cases may resolve in 1–2 days, but acute or swollen limbs need a vet.

    Urgent

    Coughing in Dogs and Cats

    Coughing is never normal. It can signal infection, heart disease, lung disease, or a foreign body.

    Emergency

    Seizures in Dogs and Cats

    Seizures always require veterinary evaluation. A seizure over 5 minutes or repeating without recovery is status epilepticus and life-threatening.

    Urgent

    Blood in Stool in Dogs and Cats

    Bright red blood usually points to the lower bowel; black tarry stool to the upper GI tract and is often more serious.

    Urgent

    Pet Not Eating

    Cats should not fast for more than 24 hours — hepatic lipidosis risk. Dogs over 48 hours need a vet.

    Emergency

    Rapid Breathing and Panting

    Laboured breathing in cats is almost always an emergency. In dogs, panting is normal in heat, exercise, or stress.

    Monitor

    Constant Itching and Scratching

    Persistent itching wrecks quality of life and usually means parasites or allergy. Needs a combined approach.

    Urgent

    Weight Loss in Pets

    Loss of more than 5–10% body weight in a month without dieting warrants a full work-up.

    Emergency

    Changes in Urination

    A male cat unable to urinate is a life-threatening urethral obstruction. Any urinary red flags need immediate care.

    Monitor

    Bad Breath in Dogs and Cats

    Persistent bad breath almost always means dental disease or illness — it is not normal aging.

    Urgent

    Eye Discharge in Dogs and Cats

    Clear tears from wind or dust are normal. Pus, blood, or squinting needs evaluation.

    Urgent

    Pet Scratching Ears and Shaking Head

    Constant ear scratching and head shaking almost always means otitis or ear mites. Treat only after a vet exam.

    Monitor

    Sneezing in Dogs and Cats

    A single sneeze from dust is fine. Repeated bouts with discharge or lethargy need a vet.

    Monitor

    Runny Nose in Pets

    Colour and side matter: one-sided bloody discharge needs to rule out a tumour or foreign body.

    Monitor

    Hair Loss and Alopecia in Pets

    Seasonal shedding is normal. Bald patches, scaling, and itching need a dermatology work-up.

    Urgent

    Shaking and Trembling in Pets

    Trembling can come from cold and fear but also signals pain, hypoglycaemia, or poisoning.

    Urgent

    Drooling (Hypersalivation) in Pets

    Excessive drooling almost always means nausea, oral pain, or poisoning.

    Urgent

    Constipation in Dogs and Cats

    No stool for over 48 hours warrants evaluation. Cats can develop megacolon; dogs may have an obstruction.

    Emergency

    Bloated Abdomen in Dogs (GDV)

    Acute bloat in large dogs is gastric dilatation-volvulus (GDV). Without surgery within 4–6 hours — fatal.

    Urgent

    Excessive Thirst in Pets

    Normal water intake is up to 50–60 ml/kg/day. Regular excess needs blood and urine testing.

    Urgent

    Fever in Pets

    Normal for dogs and cats is 38.0–39.2 °C. Above 39.5 °C is fever; above 40 °C — urgent vet.

    Monitor

    Dog Scooting (Anal Gland Problems)

    Most often this means full anal glands. Less commonly worms, allergy, or skin irritation.

    Emergency

    Jaundice (Yellow Gums or Eyes) in Pets

    Yellow tissues are always a serious sign — liver injury, haemolysis, or bile duct obstruction.

    Emergency

    Swollen Face in Pets (Allergic Reaction)

    Facial swelling usually means an allergic reaction to a bite or drug. Risk of progressing to airway swelling.

    Urgent

    Tick Bite in Pets

    Ticks are active in Russia from March to November. They transmit babesiosis, Lyme disease, ehrlichiosis.

    Monitor

    Pet Eating Grass

    Eating grass is common and often harmless. Regular vomiting afterwards points to a GI problem.

    Emergency

    Hind Leg Weakness in Pets

    Acute hind limb weakness or paralysis is a neurological emergency. Every hour reduces recovery odds.

    Monitor

    Excessive Licking of Paws or Belly

    Persistent licking of one area is almost always a sign of discomfort: itch, pain, or anxiety.

    Emergency

    Bleeding Wound in Pets

    Heavy bleeding is life-threatening within minutes. Main job: stop the bleed and get to the clinic.
