My guys love dog food but, I know it has way too much fiber and not enough fat for ferrets. Here is what I do. My guys are free roam but caged at night. When they go to beddie bye in their cage I bring out the dog food for the dogs. In the morning before I let the little rascals out, I put the dog food up where they cannot get it. I leave the cage door open so the ferts can always get to their food and I put Ferretone on their food. They will eat it with Ferrettone. Now don't let the little rascal guilt you into letting him eat the dog food. I would also be worried about fighting the dog for food. My dogs will nip hard if anyone approaches their food and that could be dangerous to a fert. I hope that helps. Kim the Oregon one [Posted in FML issue 3654]
