I agree with the other reviewer. They don't even deserve one star. This is probably one of the worst vet hospitals in Denver. After finding another vet office, I learned from several other vets that Columbine Animal Hospital is well known for recommending unnecessary procedures and treatments. My dog caught a virus at the Furry Scurry and $2000 later... They kept her overnight, recommended tons of medications, etc. She recovered so I am thankful for that. I have also learned that the overvaccinate pets. We were taking her in for shots every 6 months (did not know any better) until they gave her an overdose and she nearly died. I had taken her in on a Saturday and a few hours later, she couldn't walk, stand, anything. I was completely freaked out and called them, and learned that they were not open in the afternoon but that I was welcome to bring her in and pay for an after hours treatment. What could I do? Of course I brought her in and again, this woman vet says, oh we need to keep her overnight, etc. etc. which I knew she did not need (I had talked to a breeder friend of mine) and I knew that she only needed an antidote and be brought home to rest. This lady proceeds to work up three estimates of care and suggests I choose. $500 $1000 $1500. FOR THEIR MISTAKE? If you love your pet, I would never recommend that you take your animal to this facility. Not only will they charge you an arm and a leg, they recommend and administer treatments that are dangerous for your pet.
