Service Dog In Training Registration for Casper

Casper is my hearing service dog. He is a Yorkshire Terrier 3 years old, blue black tan colour. Casper lets me know when someone is at the door, a vehicle driving by, when the fire alarm goes off, and he tries to let people know I need help. Casper is also my husband and I family pet. Casper also is very protective. February 2023 Casper is doing well, but I need to continue his training for my Hearing Service Dog, Therapy Dog, and PTSD.
