What Our Clients Are Saying


Allyson H.

Dr. Winthrow is the most caring vet. Our 11.5 year old dog had his Spleen removed last Thursday. They sent our dog home too early. He was laying in his drool and couldn’t lift his head. I panicked for good reason. Dr Winthrow calmed us down, kept him overnight for observation and gave us updates throughout the night. I’m so thankful for this earth angel. We were really scared bc our dog also has heart issues. He’s home now and looking fantastic!!! Thank you to Dr. Winthrow and her staff on Friday (3/1) night.

Kaity R.

I am thankful for this ER vet we found last night. We had an emergency with our 14 year old boxer that ultimately led us to putting her down. I am very appreciative of how upfront and honest they were with how we should handle things a long with how upfront they were with the cost. We had a wonderful team working with Anna last night. And I’m thankful they gave us all the time to have with our last few moment with our baby. I really hope I never have to come here again. But in the off chance I do have to come to a 24 hr vet. I’ll only be coming here. Thank you so much.

Absolutely amazing ER! I came here when my baby Sebastian was bleeding internally from unsuspected liver cancer. Everyone was so kind and supportive and helped me explore all possibilities before determining it was time to help him cross the rainbow bridge. While deeply saddened, the process was smooth, cost efficient, and so caring of my situation. They even sent me a sympathy card that everyone signed and I couldn’t be more grateful. The urn I purchased came with a paw print and print of his nose and they’re beautiful. I miss Sebastian more than anything but I’m so thankful for the support of everyone here. ❤️❤️

Sabrina P.

This was by far the most amazing vet experience I’ve ever had. Every single person that was involved with our fur baby’s case was fantastic. They were extremely comforting during the entire process all the way from diagnosis to the day we got to pick our baby up. They took extra care of our baby and made sure we were updated very often. They even sent us photos! They made it possible for us to bring Luci home a healthy puppy again! Thank you to everyone at this vet hospital that took care of our sweet Luci!

Erica C.

Can't say enough how wonderful the staff was when it was time to end my cats suffering. It was such a comforting experience, thanks to Animal ER. In all my years of putting down animals on a cold metal table, this was like cradling my newborn. Thank you all so much.

Angela D.
