Malamute doggo pulls like a train and my back goes whenever i've got to walk both him and his bro. Personally think its cruel using a nose harness -- which the Mrs insists is the greatest thing ever -- after going on a walk with her to see, the doggo spent the whole time trying to get the nose harness off it's nose, hurting itself and wrapping the extention-lead around its legs all the time. Shit show.

Tried it with his bungie-lead and belt just above the belly and it was great, hands free etc. Just worried about long term back issues.
