This is one of the only honest veterinarians I have found so far in Vegas. I have tried almost everything in my geographic range at one time or another, from Banfield to VCA to independent vets. If someone tries to upsell me, sell me Science Diet, recommends unnecessary vaccines pushily, I'm GONE. There is just no reason to put up with people who care about money more than they care about animal welfare.
Dr. Cantwell was knowledgeable, friendly, and helpful. She diagnosed my dog with a yeast infection in his ear and gave us medication to use. The entire visit was around $160, incredibly reasonable for what I got done. The vaccinations are VERY cheap here and I really would recommend it for that, particularly because they won't act shocked/horrified when you aren't into the non-core vaccines (such as canine influence vaccine).
