I feed my pups on the tailgate. Put an ice chest or something next to it to give them a boost until they are big enough to make the jump. The truck bed needs to be a good experience for them to the point they look forward to it.
going to have to try this out...sounds like it will be easy...and I like easy...
It used to be easy to train my pups to load...but the taller bed on the 4 wheel drive has been a problem...
