I almost answered yes, but in reality I don't know if I can pick up 90 lb Niko. I weigh about 110 lbs, and I know I can pick up an 80 lb bag of concrete mix, but it's a struggle. So if I am lifting ten more pounds of weight, and if he's struggling, I doubt I could do it.
But once I carried Rosa a quarter of a mile home when she cut her paw on ice. She enjoyed the ride.
