Wow, I can't believe it that would happen to a dog 70lbs. I thought it was only b/c he was so tiny. No, I don't think you could pick up 70lbs. At least I have an advantage with that. My Sherry was 55lbs and even when her back/legs were bad toward the end, I had her in a sling to support her walking and she didn't seem to mind the cold. As a matter of fact, she loved the snow so much it was sad that she couldn't roll around in it like she used to. She was a Shepherd/Collie mix. Thanks for the tip. I'll do that. Right now, I have papers down in the kitchen in case he has to go.
