This is not a list of emergency hospitals: for an emergency, call the nearest emergency veterinary clinic.

Every Connecticut city we list is on the Connecticut page, and the national list is at the full directory. If nothing here fits, a licensed veterinarian will answer a written question free, which is often the fastest way to find out whether the drive is worth making.
A practice appears here only because its own website says it posts Sunday opening times, which can change without our knowing. We have not tested anyone's skill and this is not a recommendation. Listings without the PawsRx Verified badge are compiled from public records, have not been verified by PawsRx, and are not affiliated with PawsRx. PawsRx is a technology platform and does not provide veterinary care.
