First let me say...she is adorable! Now I gotta tell you, if she becomes too much for you..I'll send you my address.
Next..Spend the money & get her a really good food. These pups don't eat much so a bag will go a long way. Ask the people here about food, they have them & know best. Don't ask your vet...mine had my boys on Science Diet.
How much pumpkin?
