Roxy was 2.1 at 6 months old when I got her. She too had hypoglycemic episodes were she was younger at the breeders. When I got her, she was to get a little honey 2x a day. Which I switched to Nutrical. The first couple of months were scarey for me, as I never had a dog before, let alone 2 tiny pups. TJ was 1.8 at 13 weeks.
Roxy had 2 episodes, not sure what they were, maybe low blood sugar, or terrified of something. Anyway it scared me. I always had Nutrical, Kayro Syrup and Pedialite on hand.
Today Roxy is 5 lbs and 4 years old. She grew to 5 lbs at around 1.5 y/o
(Her best weight is probably around 4 1/2 lbs) But we love her anyway
