Need to put wieght on my dog?

I have a 3 year old Alaskan Malamute. I would like got get some weight on her for winter. I have had her on Timberwolf, Solidgold, Eukanuba. She get sick on Purina and Iams. Nevaeh is about 65 lb, so she not skinny. But she is going to pull a sled this year. And we jog 4 mile a day. I like the looks of Evo. Has anyone feed Evo to there dog and did u like it. I like how it has high protein, cause she is a working dog. Thank You
