I think you should buy a hands free retractable dog lead. This is a very cool leash for those people who love to play sports with their pets. For example, if you want to run with your dog, you can put the handle on your wrist and nothing will interfere with your comfortable body movement. You're welcome.
I also often go in for sports with my dog, we run together, we go to sports grounds. But recently, she began to bark very strongly during morning runs. Even some remarks began to be made. I decided to read the information on how to deal with this problem, I found a lot of information here https://mypetguru.com/how-to-stop-a-dog-from-barking/ and the answer to the main question why dogs bark. I think it will work.
