the aussies yes, they are around 40lbs each, but carry them a distance? I don't think so.
Masi weighs in around 73#, unless my adrenaline was really pumping, I doubt I could pick her up.
With Dodge when he was here, he was around 80-85#, had mobility issues towards the end, he was a smart cookie (and Masi is learning the same thing for future reference!),,he would put his front feet up on whatever, (car, couch, bed) and wait for me to boost him up..As for picking him up? No way. Going upstairs at night, cause god forbid the dog didn't sleep with me every nite, I had a harness type device, that had handles on the front and back,,I'd take the front and hubby would take the back, we'd guide/stablize/ haul him up
If the dog was "down", and I had to move him, I'd most likely use some type of tarp, blanket get them on it, and drag them but actually lift them off the ground, couldn't do it
