Contact a vet immediately.
Urgent warning signs include breathing difficulty, collapse, seizures, severe bleeding, suspected poisoning, a swollen abdomen with unproductive retching, inability to pass urine, serious injury, extreme pain, or signs of heatstroke. Phone your veterinary practice or its out-of-hours service while arranging travel.
Seek prompt advice.
Contact your vet if your dog has persistent vomiting or diarrhoea, refuses food or water, seems unusually quiet or distressed, develops eye problems, has a painful or worsening skin condition, or shows a marked change in drinking, urination, movement or behaviour.
Prepare useful information.
Be ready to describe when the problem began, changes over time, medicines, possible toxins or unusual foods, and any relevant photographs or packaging. Do not give human medicine or try to make a dog vomit unless a veterinary professional directs you.
This page cannot assess urgency for an individual dog. If you are unsure, contact a veterinary professional. In an emergency, seek veterinary assistance immediately.
