I am so grateful that Dr Brittany assisted Mandy and me as we sent her across the rainbow bridge. Dr. Brittany was so patient and kind with all of us. I cannot express how much I would suggest Coda Pet and Dr. Brittany to anyone who needs to assist their pets at this terrible time. They are the help you want to be there with you. I am grateful I found this option..

We are deeply thankful to Dr. Shannon Nakaya for the care and compassion she showed during our beloved dog Giggsy’s final moments. Saying goodbye was an incredibly painful decision and a very difficult day for us, but her kindness, patience, and gentle approach helped ease the burden. Dr. Nakaya guided us through the process with understanding and treated Giggsy with such tenderness and respect. Her compassion and professionalism truly made all the difference during this heartbreaking time.

We had to say goodbye to our pup Leo, who we had for 16 years, and it was one of the most painful things I ever had to do. Leo had advanced kidney disease and his health quickly deteriorated. We had scheduled a Coda Appointment with Dr. Derecka Alexander for a Tuesday, but Leo’s health took a turn for the worse on a Sunday. I emailed Coda Pet to ask if there was any possibility any Vet could come out sooner. Dr. Alexander immediately contacted me and made herself available in our time of need. We were so appreciative of Dr. Alexander’s compassion and kindness in helping our beloved pup Leo cross over the rainbow bridge, especially after it became urgent. She made a very difficult experience of us having to say goodbye to our pup more manageable. We chose to get a Vet to come to our home for our final goodbye to our Leo because we wanted him to be surrounded by the warmth of our love, the comfort of his family, and the smells and sounds he has always known. I wanted his last memories to be of us — his family — holding him, kissing him, thanking him. Thank you, Dr. Alexander, for allowing us to provide that to our pup Leo.

Dr. Christina came with such a passionate and sympathetic heart her love for animals and for animal parents is unmatched. She went above and beyond to give us extra time to say goodbye to our dear Maggie Mae and even let our other dogs in to say their final goodbyes as well. I highly recommend Dr. Christina for any emergency animal euthanizing her care and passion even dropping Maggie Mae off was just been above and beyond. Thank you, Dr. Christina for your love, your passion and your overall professionalism during this difficult time.

We decided to use CodaPet when it was time for us to make that decision for our sweet 14 year old St Bernard, Fiona. It was the best thing we could have done. Dr Jason Doolittle made sure the experience was peaceful and went at a pace we were comfortable with. He explained in detail everything that would happen and was very gentle with Fiona. Thank you for providing a service that allows our fur family to go peacefully in their homes surrounded by comforting faces and love.

Dr. Gordon performed the euthanasia for my sweet soul dog of 16 years. It was the most peaceful experience I could’ve asked for. She knew exactly what to say and created such a calm environment to spend our final moments together. I’m very grateful for her service.
