12 weeks is probably the optimal age for the puppies to be before they leave their breeders. But many breeders are giving them away younger. I don't blame the buyers for that, if they don't know better. When we got our puppy, she was 12 weeks and I had no idea they shouldn't be younger than that, and was a bit disappointed that she wasn't younger, silly me.
Anyway, I'd say, mix rice into whatever the puppy will eat. The main thing is to get them to eat often enough so they don't get hypoglycemic, and try to give them as much nutritional stuff as possible. |
