Our Practice

Companion Animal Clinic has the distinction of being one of the most well established veterinary facilities in North County San Diego. We have proudly served our community for about 40 years and have been under Dr. Knox’s leadership for more than 20 years.

We are a general dog and cat practice that offers both Western and Alternative care in an integrative way. We believe that INTEGRATIVE MEDICINE is the ideal approach to medical care. Please CLICK through our site for more information about our INTEGRATIVE CARE!!!

Dr. Knox and his excellent team dedicate themselves to the care of your furry family members through care, compassion, knowledge, and service. We do all of this while keeping our integrity as the primary guiding force. In fact, our Mission Statement is just that.

“Care, Compassion, Knowledge, and Service…with Integrity”

We believe deeply in all of these principles and we want to make sure that we show you each of those characteristics at every encounter.

If you prefer a veterinary experience that loves your pet, explains things to you until there are no more questions, and wants to foster a sense of trust with you, PLEASE CALL US today at (760) 743-2751!
