This Dog harness is absolutely beautiful and unique! Although my dog is a puppy right now so it doesnt quite fit him as of right now but once he grows a little bigger its going to fit him perfectly. I believe just by the weight and material of this harness its going to keep him on lock meaning your going to have a good hold of him. What i also like about this harness is it is thick he will not be able to escape out of it. Like the harness i have now it is thin material and thinly made. Definetly check this harness out especially if you own a pug, pitbull broad shoulder dog u will be very satisfied with ur purchase.
