San Diego

My dog had an infection in his private area and a lump ( turned out to be a cyst). I thought the infection was due to a foxtail. They probed three spots and removed the lump brought all shots current full blood panel and meds under 750. Very affordable They had an excellent system for dealing with COVID social distancing and taking your pet. Dr Stevens was great. They are my new veterinarian. I already use muddy paws for boarding and grooming this will make a complete one stop. I also live in Escondido but the drive is well worth it.
