He's using the raw frozen(chicken) patty. It's got everything in it.
The way I see it, the dog was outside, it's cold, dog shiver its fat off. He started off with the dog being under weight. Dog gets worked out, fed and stays outside. 30 days later, the dog looks like shit, it's getting closer to show date and all he does is try to give dog more patty. Dogs stool is loose and he ran out of ideas.
With that thin of layer of fat on the dog, there's no way the dog could make weight even if he is fed all the food suggested above. He needs to bring the dog inside. It's the only way it'll make weight.
I live in the coldest part of the US. I have to deal with this weather every year. Putting one in a keep at below temp is my specialty.
