She is very happy indeed. Just got back from a couple hours at the beach today, whee!
Anyway, I took her to the vet for a weigh-in last month. She checked in (after a big ol' poop around the corner) at 19.7 pounds! I could not tell the difference with my eyes, and I really didn't think I'd been cutting back so much… the vet should have no complaints now. Her appetite and energy levels are normal, her skin and fur are nice... I guess I'll keep doing what I've been doing, but she can get raw eggs twice a week again and I won't feel so bad about slipping her an extra treat every now and then.
I thought these were interesting pictures of her loose skin from around the time I weighed her last month:
The only thing now is I have to watch it even more carefully with the Comfortis, since both dogs were given the dosage for 20-40 pounds. I wasn't giving her the full pill anyway since I've heard of several dogs react badly to it when they were at borderline weights. And she is borderline, with weight that apparently fluctuates more than I can easily perceive.
