We are heartbroken to share that our beloved office dog, Emi, has unexpectedly passed away after a sudden illness. ❤️‍🩹

Emi brought comfort, smiles and joy to our patients, families and our team. She was much more than our office dog - she was a cherished member of the Arch Orthodontics family.

Thank you for loving Emi as much as we did and for your kindness and support during this difficult time. Emi will be deeply missed and forever remembered. 🐾🩷

If you have photos of Emi please share in the comments!
