Pulling harness and what size?

[lil_bit807]

I have been looking at pulling harnesses on the O'brien's website. I have a rednose female that weighs between 70-80 lbs. I don't know if I should get her the medium harness (60-75 lbs) of the large harness (75-100 lbs). Will she lose wiehgt as she gets into pulling? I just don't want to get one and it be too big or too small. any help with this would be greatly appreciated. Thank you in advance.

Actually, find a good, reputable person/business that custom makes weight pull harness. They will give you instructions (complete w/a picture diagram for help ;) ) on how to measure your dog so that the harness fits him properly.

Since every single dog is different, no matter the weight, it doesn't make sense to use a "one size fits all" harness on him. An ill fitting harness can cause problems by a) rubbing the dog & creating sores in places & b) not distributing the weight in the proper areas thereby increasing your dog's chance of serious injury.
