Petscan was established in 1989 to provide a reliable mobile nationwide ultrasonic pregnancy detection service for animals. It is the only mobile service to cover the whole of England and Wales. We offer a reliable pregnancy detection service in dogs and cats, from as early as three weeks gestation (although pregnancies can be detected earlier on a real "need to know" basis.) We will come to you or you are welcome to come to us at our base in Milton Keynes.
