First of all, some yorkies are just going to be very small and petite because of genetic, as long as the vet says their vitals are OK, then don't worry as long as the appetite is good and he is hydrated. These are the "teacups" that everyone talks about, they are just dogs bred to be really small or runts.
If he truly needs to put on some lb's, I swear by nutri-cal and "satin balls". Nutrical is found in many pet stores and online and the recipe for satin-balls is also readily available online. Many rescue organizations use satin balls to fatten-up malnourished rescues. |
