I've noticed that dogs, including Basenjis, eat more and get chubby if they were abandoned and lived in the streets for a while, especially when they were young pups. One of my Basenjis and one of my rescues have cast iron stomachs, they aren't picky eaters, and they love food! One of my Basenjis doesn't eat a lot and I often hand feed her so I know she is getting enough nutrients.
