Dogs can’t tell us when they feel unwell, so it’s vital for owners to spot subtle changes in behaviour, appearance, or habits. Early detection can save lives, prevent complications, and ensure your dog receives treatment quickly.

Our Top 10 Signs of Illness in your dog
Lethargy or Weakness – Observe if your dog seems unusually tired, avoids play, or struggles to move. Check if they are slower than normal on walks or have difficulty standing. Encourage hydration, and note any changes.
Loss of Appetite – Track daily food intake. If your dog refuses meals, snacks, or shows disinterest in treats, note the duration. Offer bland food and ensure hydration. Persistent refusal after a day requires attention.
Vomiting – Monitor frequency, colour, and contents. Note whether vomiting is accompanied by diarrhoea, lethargy, or repeated attempts. Avoid giving food for a few hours, provide water in small amounts, and tell Max and your vet.
Diarrhoea – Observe stool consistency, colour, and frequency. Persistent diarrhoea or constipation can indicate dietary issues, infection, or underlying illness. Keep the dog hydrated, track episodes, and tell a professional.
Coughing or Breathing – Listen for persistent coughs, wheezing, or laboured breathing. Note if it worsens during activity or rest. Keep the dog calm, avoid exertion, and consult a vet immediately, as respiratory issues can escalate.
Unusual Lumps or Swellings – Feel your dog’s body daily for bumps, swelling, or asymmetry. Monitor size, shape, and texture. Do not attempt to squeeze or treat lumps yourself. Report any changes to your vet.
Check your Dog's Skin or Coat Changes – Check for rashes, redness, bald spots, scabs, or excessive scratching. Note any odour or discharge. Ensure the dog isn’t licking wounds excessively. Persistent skin problems can indicate allergies, infections, or systemic illness.
Eye or Nose Changes – Observe discharge, redness, cloudiness, or swelling. Note changes in pupil size or colour, watery eyes, or sneezing. Wipe gently with a clean cloth if mild, but seek veterinary advice immediately for persistent or severe changes.
Changes in Drinking or Urination – Track water intake and bathroom habits. Sudden increases or decreases may indicate diabetes, kidney issues, or urinary infections. Record frequency and volume. Contact a vet and tell Max if changes are sudden, persistent.
Behavioural Changes – Watch for aggression, hiding, whining, or confusion. Notice if your dog avoids contact or seems disoriented. Behavioural changes can indicate pain, neurological issues, or systemic illness. Do not punish; observe, record, and consult a vet promptly.
