Even my nervous, anxious cat did great with his first visit here!! I was so happy with the service, patience and empathy that the staff showed. My furry boys will definitely be coming back, and not just for the yummy treats!

I have been taking my cats to Companion for the past 25 years and almost always had great experiences. Times were certainly better when Drs.Mac and Earl were in charge. Too much commercialization and transient vets these days. Thankfully Dr. Earl still comes in and we had a great visit with him this week. 😀

Took my dog here yesterday because woke up and my dog pee'd blood on her pee pad. They did no tests of any kind, said it was a UTI. Gave her a shot and sent us home. I collected a stool and urine sample because her condition was not getting better. Took her back this morning, they still ran no tests but said that she could have eaten rat poison but did not offer treatment. Now my dog is at another vet and they x rayed her and found a large blood clot in her kidney. She is declining and may die. With poisoning in pets timing is extremely crucial. Very sad that an "emergency Vet Clinic," could not run a single test to identify the problem. My dog may die now because of their dismissiveness. Do not go here.
***Update: my dog passed away due to an aggressive form of bladder cancer. It is likely that if the Vets here did their job correctly my dog still would have passed away. The point is they did not do anything. Then they called and tried to pressure us into changing our review. I stand by my review, please do not take your pet here for anything more than routine shots. ***
