Its not accepting ANY new clients at all! Even if you can pay! So my lil baby is not well & she's almost 12, pretty sad & disappointing a vet that won't heal or even examine her!! That's just cruel. One star was me being very generous. Rude & rushy on the phone & my lil dog is in bad shape! Terrible treatment. Oh wait terrible NO treatment!!"HATED IT!!!"...👎🐃💩💔🤥🚫🐶❤🤔🐾🆘🛐🙏🙏

My 3 Year Old German Shepherd Jet needed to be seen for an Emergency, the staff is wonderful & was able too see Him in 2 Hours! When I take Jet for His Appts there, He gets excited because everybody there Luvs Him! The Vet called Me after the Exam & explained my Options & the Cost of Jet's treatment for Inflammation of His Colon! The staff explained Jets Medications & Special Diet to Me & called the next Morning to see how Jet was doing! 🐕‍ Theresa & Jet🐕‍

My neighbor cat Murphy Huston has been off and on not feeling too good. He's 14yrs and has health issues, some days are better than others. The Doctor and nursing staff here are outstanding in every aspect. The take great Covid Precautions
They are sweet, knowledgeable, empathetic, and quick on their feet. I've not had this type of 1 on 1 compassionate care provided to me by past doctors as they do there and happy to do so.
I recommend this facility to anyone

I like the way the staff treats me. They address my concerns. Dr. Duff is my personal favorite, but Dr. Lambert is great too. They have taken care of all my animals for about 4 years now. 4 Dogs and 2 cats. When our seniors passed away they made a donation in their names to a place that keeps senior dogs from having to be in the pound. Overall awesome. Sometimes a little pricey for the area though.
Update:
I had an issue with my cat and her well shall we say her privates. I took her to the vet three times, had blood work done and an ultrasound to find out she was to fat to clean herself. After

I've been to several vets for my two dogs and have always felt the doctors were trying to upsale me on everything! Then I found this gem of a place where every single employee made me feel good about bringing my babies there to get checked out. My first experience here was with my pit bull who is very old and incontinent. The doctor didn't make me pay for an expensive urine test, she just filled my prescription for Proin. She explained she will need to do testing though after a year and that was totally fine. Then I took my tiny dog to get her teeth cleaned and some teeth extracted

I would NEVER recommend them to ANYBODYYY. Obviously, they're just in it for the money and don't care about your pet! Our entire family is disgusted by the fact that they prescribed over 250 dollars in medication instead of doing blood work to diagnose the problem. If I could rate zero stars I would!

They charged us twice for dog food that we did not receive, and the medication they gave us has not fixed anything. Instead of leaving with answers, we left with more problems and less money.

Not to mention the fact that the nurse was very unprofessional, unresponsive, and pumped our pet

Love love love it here. I've been here for my tortoise and when my in laws dog had to be put down, then again today for my 12 year old pit who had a seizure out of no where. Karen up front, awesome. Dr Lambert, awesome. The tech, I believe her name is Tiffany, awesome! They got me in for an emergency right away even when their lunches were on the line. I really cannot say enough about this place. Clean, kind, patient and welcoming. Other than my poor girl there was nothing I didnt like about this clinic! Thank you ladies!!

My dog and I had a great experience getting my dog's health checkup before his international flight to Japan. All of the staff was very helpful and friendly, and especially, Christina at the front desk and Dr. Brie Duff were amazing! When I made an appointment, Christina emailed me with some useful info about the USDA APHIS beforehand, about which I was not aware, and at the clinic, Dr. Buff powered through the annoyingly complicated documents I needed to submit to the quarantine in Japan. Besides such an amazing service, they were very patient with my yappy little dog who oftentimes gets

The front desk operator Christina was very helpful and understanding when I called trying to book an emergency appointment. I was sad I could not be penciled in, but Christina nicely directed me to another vet clinic that does emergencies. I accidentally wrote down the wrong number so I needed to call Clearlake Veterinary Clinic one more time to get the correct number. However this time Heather answered and when I began to ask her questions she was very insensitive to my situation. She interrupted me twice to rudely tell me there were no emergency openings at her clinic, when i wasnt trying to

Twice our little dog needed some help feeling better. They are great! Offered to do everything under the sun, but didn't flinch when I broke it down to what I felt was necessary. Made it so our Oswald felt better...but if we needed to bring him back, the door was open. The 2nd visit was an emergency walk-in, first thing in the morning. They took care of Oswald, even though only one doctor was available. Great service!

Found a teeny tiny kitten on the road on a Friday evening. These nice folks helped me take care of her that very night as a walkin. They are compassionate and helpful. They have weekend hours so working pet owners can get care without missing work. They are careful to explain costs so pet owners can plan instead of being socked with a big unexpected bill.

I work in human healthcare. I would say if this office took care of two legged patients that they were a good practice. This is a good vet practice.

Although we only live a couple of miles from our one-and-only-had-a-couple-of-bad-experiences local pet hospital, we choose to drive 35 minutes down the road to Clearlake Veterinary Clinic. We know, not exactly environmentally-friendly, but hey, we're really good recyclers!
Clearlake Veterinary Clinic is affordable, the doctors and vet techs are completely competent, the staff is professional, and as long as we live here, they will be our further-away-than-we'd-like vet clinic of choice.
We recently had to say good-bye to two of our companion animals within weeks of each other. The

I have been going to this veterinarian for the past few years. The staff is truly wonderful, and you can tell they love animals. My boy's (chihuahua and pug) have been treated well.

Best veterinary clinic in Lake County.
