Thank you for not declawing cats! Any veterinarian who does not perform barbaric outdated unnecessary p3 toe amputations on a once healthy cat is tops in my book. I take my cats and dogs to a veterinarian who does not declaw cats, even if I have to travel an extra 20 minutes, it is worth it, they don’t cry and whine in the car anymore like they used to when we used our ex-vet who declawed. Animals are sentient beings, not property for humans to mutilate. No wonder they used to cry on the way to our ex-vet, they were wondering if any of their body parts were going to get amputated.Donna D.
I wanted to update my review. Previously on here, I mentioned that I had a sub-par visit at The Pet Doctor. I have to say that I spoke with the staff and Dr. Hammerle and I have never felt more valued as a customer. She called me personally to discuss the issue and it was resolved very fast. Nara LOVES the staff there and they have the best interest at heart. I have never been treated so well by a vet clinic.
Dr. Hammerle values every client and looks at building a lifetime client and I will take my current, and future pets to The Pet Doctor.
Thank you for seeing Nara and thank you for making me feel like I have a voice within your company. I know you and your staff genuinely care for my dog and what is best for Miss Nara.Melanie T.
My cat, Dave, was brought into the clinic because of a cancerous mass in his mouth. Marcy took a look and said it was definitely removable. They took such great care of my furbaby. I would probably still be in tears today if it hadn’t been for them. They are a wonderful team!!! They called the day after surgery to see how he was doing. Marcy, you’re awesome! Thank you all for everything! P.s the facility is amazing!Kim B.
