In a deeply personal post, Fallon reflected on what Gary meant to their family, opening with a line that perfectly captured the weight of his heartbreak:

“She was the last name we signed on every birthday card.”

From there, Fallon painted a touching portrait of a dog who was so much more than a pet.

“She was our first baby, a therapist, a pillow, a big sister, a schoolmarm, a comedian, a party girl and [sic] a rebel.”

Accompanying his emotional words was a carousel of photos showing Gary’s beautiful life, from playful puppy days to cozy family moments.

One image showed Fallon lying beside her on a bright orange rug, the two perfectly at peace. Another showed Gary surrounded by Fallon’s wife, Nancy Juvonen, and their daughters, all smiling and adorned with flowers.
