Verified Greenwich veterinarians and animal hospitals for routine wellness exams, vaccinations, dental care, surgery, and emergency and after-hours pet care - serving Old Greenwich, Riverside, Cos Cob, Byram, Glenville, Belle Haven and beyond.
Before you pick a vet, ask three things: do they see emergencies and, if not, which 24-hour hospital do they send you to; who answers the phone after hours and on weekends; and how they handle a first visit with a nervous pet. A good clinic tells you plainly when something can wait until morning versus when to come in now, gives you a real estimate before treatment, and takes the time to let an anxious dog or cat settle instead of rushing the exam.
Searching for veterinarians and animal hospitals near me in Greenwich? Everyone ranked below serves Greenwich and the surrounding neighborhoods, including Old Greenwich, Riverside, Cos Cob, Byram, Glenville, Belle Haven.

If this is an emergency, call rather than fill in a form. A pet that is bleeding, struggling to breathe or has eaten something toxic is the case for calling instead of waiting for morning. Ask up front whether they are dispatching tonight and what the after-hours call-out fee is: 24/7 availability is not something a star rating can tell you.

After-hours availability is not part of a Google rating, so this directory cannot verify it for you in advance. A pet that is bleeding, struggling to breathe or has eaten something toxic is the case for calling instead of waiting for morning. Call the top rated veterinarians and animal hospitals on this page and ask two things before you agree to anything: are you dispatching tonight, and what is the after-hours call-out fee. A company that answers both plainly on the phone is usually the one that actually shows up.
