My girl is way too thin. Her spine stick out and I can easily feel her ribs (ironically my boy is chunky). I am in the process of changing from chicken soup puppy to canidae as I was wanting my male to lose a little bit and I figured puppy food has more calories. (Turns out canidae has more cals than chicken soup puppy). But anyway, she will hardly touch it and I want to know what people foods I can feed her to put some weight on? I am pretty much a vegetarian myself and I do not cook much, so keep that in mind (no boiling chicken, etc.).
Does anybody have suggestions on foods I can healthily give her and that are simple require little to no prep.

Thanks!
