Help Keeping Weight on Dog that Works Out

[WendyWayne]

This may be moot in a few weeks after Badger's last pull, but I cannot keep weight on him! He looks like an ABDA dog LOL. He's outdoors and it is getting cooler and he works hard at pulling a few times a week. I feed him kibble mixed wth things like eggs (raw) vegetable oil, some raw, leftovers, yogurt, etc. He also loves his veggies, will pick the raw veggies out of his bowl and eat them first. I feed him a lot, maybe even 6 cups a day.
