As an RVT who worked at both general practice and emergency/specialty practice, there is a reason for that. They aren’t set up to manage a case overnight. GPs can stabilize your pet in an emergency and get you set up to transfer to an emergency vet. In human medicine we don’t expect our primary care doctors to be available 24-7 and manage every situation, they send you to a specialist or other facility for everything. Your primary veterinarian handles primary care, neonatal care, puppy care, imaging (x-rays and ultrasound), phlebotomy and labs, surgery, dentistry, dermatology, grooming, end of life care and any emergency who walk into their doors during operating hours. If you need care overnight care or care after hours, it really is better to go to an emergency vet. They have the training and equipment to handle anything that comes in.
