Hi
My dog is small its mix and it would not eat she is under like 13 pounds she would not eat her food I give her dog food and I give her human food she would sleep and day and not do that much she got all of her shoot I just don't know what to do so can you help me

Since she isn't eating and losing weight, take her to the vet. Could be a number of things... possible infection or illness, possible obstruction, maybe age related, etc..

Maybe she doesn't like the food you give her

Because he is getting exercise

How would that help by give her a little of food
