Canyon Hills Animal Hospital and Specialty Center

NOTE: It was explained to us by the seemingly benign receptionist--that her father once owned the clinic and sold it to Dr. Marquez. So, please understand that the 'pricing' is a game of tag between the front desk and the Dr. that looks you in the eye as your dog is suffering and throws prices at you. We arrived on a Saturday as our 'Vet' was closed and couldn't handle the emergency as it was being experienced. Fullerton Animal Hospital sent us 3 to 4 names of locations designated as 'open on weekends' --but were their recommendations for ER Vet. (I add that because Dr. Marquez tried to say she wasn't an ER Vet when I was speaking with her about her bedside manner on the telephone.) Dr. Marquez, took our dog out of the examine room and ran some bloodwork. She came back and said that she was pretty certain it was Addisons and that she would need to run another diagnostic test to confirm that it indeed was this life threatening condition. That is, unless we wanted to spend an additional $600-700 dollars plus for an ultrasound/mri. She performed this diagnostic that was supposed to measure the spike in cortisone levels, returning to confirm that our German Shepherd that was just seen one week prior by a Vet that said he was healthy as a horse--had Addisons and needed to be on Fludrocortisone and Prednisone for the rest of his life. Then we were scheduled a follow-up to test his levels after he had been on the treatment plan for about a month. There was a slight adjustment to the Prednisone and Fludrocortisone. It wasn't until our dog experienced another 'crisis' --that the Dr. NEVER EXPLAINED PRIOR TO OUR EXPERIENCING THEM, that we needed to return to see Dr. Marquez. She wasn't there for the last visit. No, instead I needed to call her because the levels that she had prescribed were not working and when I adjusted the Fludrocortisone our dog was more active. She denied I understood the condition and insisted our dog was experiencing the effects of a 'secondary condition'. Well, it is entirely possible that our dog was experiencing a secondary condition because the regimen of Prednisone (steroid) over a long period of time will cause internal bleeding and possible organ failure. Dr. Marquez never explained the condition or the side effects of the medications that she is licensed to prescribe. In fact, she got irritated and confrontational as I questioned her ability to describe my dog's condition since she quoted the weight at which the meds were prescribed...wrong. She tried to tell me that it was my fault for not being at an appointment that she wasn't at that disqualified my interrogation. I refused to see this Vet again and our dog died during an Addisons crisis because local Vets in the area are not qualified in internal medicine. PLEASE BEWARE!!

Took our dog there at the recommendation of another vet, as she had been diagnosed as diabetic. 3 days late when we picked her up, we quickly realized she was now blind. The vet acted like it was no big deal. How is that not a big deal? It would be a big deal if the vet was the one that went blind in 3 days while in the hospital. She also had a bad sesiure that night and the next day. She had never had sesiures before. We wish we had never taken her there! Clearly, they over medicated her or something. They have no compasion and are very expensive.

I have an elderly dog with kidney disease (and heart disease, and IBD) and I had a ton of questions for Dr. Marquez. She was super patient and explained everything in a way that was easy to understand. She also went into greater detail than some other internists, which I also appreciated. Canyon Hills is letting owners come in with their pets, while many clinics in Los Angeles are still making people wait in the parking lot. My dog is anxious and old, and I wanted somewhere I could actually be present at the appointment. For this reason, and because of Dr. Marquez's credentials and expertise, I drove over an hour for the appointment. Totally worth it. Also, the receptionists and vet techs are super nice too. Highly recommend.

When I unexpectedly found out my best buddy Tally Dog had a gigantic tumor, my vet recommended Dr. Marquez and staff. Dr. Marquez fit me in for a visit the same day I found out, and was able to schedule a next-day CT scan. Within the very next week, she had determined the source of the tumor (her spleen) and that it was operable, and had Tally scheduled for surgery with Dr. Hofacre. He seamlessly removed the 5lb tumor from my 35lb dog (!!!), and talked me through her recovery process. Tally just had her staples removed today, and is back to her old bouncy, energetic self. The doctors and vet techs here are excellent, they have real caring and compassion for the animals, and the front office staff was friendly, responsive and efficient during all my visits. I highly recommend this practice, especially if your fur baby needs surgery.
