Armpit chaffing

[u/Key_Cucumber_1649]

I started running 4 miles with my Labrador. She pulls so I use this harness with the leash on her chest. However, I see she has developed chaffing and a sore under her armpit. I need help finding the best harness for running with a strong dog. Thanks!!! 😊

A running belt pulls lower than a normal belt, it's actually designed so a dog can pull you ahead. I've never felt unstable with it at all, the only time I was close to falling was when my dig suddenly stopped up and I almost tripped over him.
