Proudly Caring For


We are lucky to have an amazing partnership with NBAS. It is so important to be able to give our homeless animals medical care everyday and we are so happy that we can provide that service.

Our friends at Wildlife Rescue are doing amazing work and we are lucky to be one of the ones that they call on to help them with some of their charges.

Humane Society of Sonoma County

SHSC takes on many animals that are lost and injured. We are happy to help them when we can, often taking care of sick or injured rabbits for them.


We have been honored to treat Highway Patrol K9s since 2014. Officer Rudder and his partner "X" work hard to protect the community and we are glad to be able to provide the medical care needed to keep them working as a top notch team.

  • "We have been going to Brandner Vets for around 12 years and they are the absolute best from the front staff, dr’s, and support team. We have had two dogs under their care for this time with never a problem or concern with the quality of service. We have a 25 year history with vets and Brandner is number 1 in our book. Thank you"
    Richard Stefani
  • "Dr. Pfann was exceptionally kind and considerate when we brought my daughter's mouse in for a respiratory infection. He is a pet lover himself and his interest and compassion was evident. His fees were very reasonable. Pets have a special place in our hearts and this hospital seems to recognize that connection we all have with our animals, even the smallest and most vulnerable. We thank the staff for all their help. We wish we had known about Dr. Pfann and his staff sooner!"
    Andrea S.
  • "We've been with Brandner Veterinary Hospital for close to 20 years because of the many "Parental" considerations that inform the love and care of our beloved pet family. Brandner has provided our dog Emma and our kitties Pippi, Orca, Buster, and Mushu the finest and most knowledgeable care that gives us the comfort and reassurance that abides our total commitment to our 'kids'."
