Providing Out Of Hours and Emergency Veterinary Care

All veterinary surgeons in the UK have a responsibility to provide 24- hour emergency first aid and pain relief to animals according to their skills and the specific situation. The Royal College of Veterinary Surgeons has recently updated its guidance on emergency care which has placed more emphasis on the owners’ legal responsibilities for their animals.


In most cases the treatment of an animal will be able to be carried out most effectively by you bringing them to our Saffron Walden veterinary hospital, or taking them to our Out Of Hours Emergency Provider Vets Now in Witham, where we have all the equipment and facilities for emergency treatment.
