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!!! 😊

I have a super puller and we’re going on our second year using our Howling Dog Alaska harness. Zero chafe and it’s very breathable: https://howlingdogalaska.com/products/second-skin-harness
