PAWS For a Cause!

Our team is dedicated to providing as many pets as possible with high quality, comprehensive care. We are excited to promote our new program, PAWS for a Cause, in which we will donate $5.00 to Happy Tails Pet Rescue in Hudson, NH for every PAW Plan enrollment! Not only will you be providing your pet with wellness care, but you’ll be helping to provide that same care to a shelter pet! We believe every pet deserves preventive wellness care and want to do our part in making sure every pet can receive that care! Share our passion? Stop by and donate! Every penny towards prevention counts!
