I have an 8 week old pug puppy who is the runt and only weighs a pound and I need her to gain more weight. She is currently on under the sun puppy can food. I want to transition her to dry food. I've tried blue and she didn't like it. I tried TOTW and refused to eat it. Is under the sun puppy dry food a good brand or do you guys have any recommendations for puppy food? Thank you so much guys it'll be a huge help!
