Thanks for offering to help Randy.
I've been lifting patients for 25 years now and have the scars from back surgery to prove it.
We've got a scale we use to classify our "heavy" patients.....
Anything under 200 lbs. = normal
200-300 lbs. = "sea cow"
300-400 lbs. = "whale"
400-500 lbs. = "killer whale"
500+ "the dreaded Moby Dick"

From the pictures...I don't think Digger looks that heavy. It would be worth a framed original
