You can say goodbye to your pet in whichever way you're comfortable with. When the pet is not deceased but is about to pass away, pet owners often talk to their pets to say their final goodbyes. I always advise thanking the pet for being such a good pet, sharing a few of their favorite memories, and then saying the final goodbye. After the pet has died, some owners organize a small goodbye ceremony with only a small number of people who loved the pet the most as a way to honor the deceased pet's life.
