Yorkshire Terrier Q&A
As a breeder of these dogs, I advise a good quality Kibble with meat being the first ingredient.
the NAID does best with a diet of 30% protein, 20% fat. since many dog foods dont contain those percentages, you can also supplement additional protein and fat. good suppliments are K9-Rx and NuVet dog suppliments. for additional fat, you can occasionally give them fat scraps from your meat, just make sure it is ok for dogs (no pig i other words unless it is frozen for at least 3 weeks and cooked completely to kill any parasites). just make sure you dont give it to them right from the table as they will want more and will turn to begging at the table.
