My puppy Luna is 4 months old and is a chihuahua mix of some kind. She eats 3x/day as recommended by my vet. However, she’s starting to get sick of her dry/wet food and I’ve started to spoil her by putting a little shredded rotisserie chicken in it so she eats what is supposed to be the necessary dosage of food for her size and weight. But I know this isn’t good for her, yet she won’t eat her food if there isn’t anything humanly appetizing about it. Any suggestions for something quick and healthy I can add to her food?
