10 weeks is still so young, and I remember my first yorkie puppy having a belly
they're still growing after all.
I know set feeding times helps with potty training, but at 10wks and 2lbs, I'm not sure if that's most appropriate. I'd definately keep forti-cal (or equivalent) on hand. Maybe those here more experienced with such little ones can recommend a feeding schedule to help with potty training, but also keep blood sugar from dropping ???
