thank all of you i am going ot try the ruff wear!

My basenji loves to rollerblade with us but I have 4 different harnesses and all of them cut her right in the armpit to the point of broken skin and sores. Everytime she get a raw spot we have to wait until it heals to get her out with us again (it is a great way to drain their energy and she loves to be able to go top speed). Do any of you have a good harness that fits their small necks and large chests? Any help would be greatly appreciated.
