Read guide →Common questions
When should I call the vet immediately?
Call your vet immediately if your dog is struggling to breathe, has a visibly swollen abdomen, is collapsed or unresponsive, has had a seizure, has ingested a toxin or foreign object, is bleeding heavily, or cannot stand. When in doubt, call -- vets would always rather you phone than wait.
What is the vet emergency number in the UK?
Most UK vets offer 24-hour emergency cover or direct you to an out-of-hours service. Save your vet's number in your phone. The Animal Poison Line is 01202 509000 if you suspect your dog has eaten something toxic.
My dog seems unwell but I'm not sure -- what should I do?
Trust your instincts. You know your dog. If something feels off -- they're quieter than usual, not eating, moving differently -- it is always worth a call to your vet. Most practices have a nurse line for non-urgent queries.
Can I use these guides to diagnose my dog?
