Food and appetite

When your pet will not eat or food no longer suits them

Appetite changes can come from preference, environment, dental pain or illness. Check the whole condition instead of changing products repeatedly.

Check first

Call a veterinarian promptly if loss of appetite comes with repeated vomiting, breathing trouble, collapse, a swollen abdomen, severe pain, suspected poisoning or inability to drink. Young, elderly and chronically ill pets may need earlier care.

What to do now

  1. 1

    Record when the pet last ate and drank and whether urine, stool, vomiting or behaviour changed.

  2. 2

    Check the food’s expiry date, smell, storage and any recent change in product or amount.

  3. 3

    Offer the usual food in a quiet place; do not force-feed or give unsafe human foods.

  4. 4

    Contact a veterinarian if the change is sudden, continues, or is accompanied by other symptoms.

Choose the right kind of help

Usual complete food

Start by checking storage, portion and routine before changing a diet that previously worked.

Diet change

Transition gradually unless a veterinarian instructs otherwise, and watch stool, skin and appetite.

Veterinary diet

Use for the intended condition under veterinary guidance; do not substitute based only on online claims.

Prepare before you contact anyone

  • Food name, flavour, lot or package photo and daily amount
  • Last normal meal and recent treats or human food
  • Water intake, urine, stool and vomiting
  • Weight change, dental signs and other symptoms
  • Medical conditions, medicines and previous diet reactions
