Dear Vet,
Thank you for your kindness to Sam and myself on XX XX 2012. You have always provided such great care of all my animals. Saying goodbye to Sam was heartbreaking, but the compassion that you and your vet tech showed to us both helped carry me through this time. I feel blessed that Sam was in such good care, including his last visit.
Thank you also for your thoughtful card. I appreciated you kind words and thoughts.
Reader, and cat and dog (names removed to protect the furry)
I also like Moray and Amara's words. Like Webhill, I'm sure your vet will be touched to receive a card from someone who appreciates the care that they have shown your furry friends.
