Training is all I am doing for the past 2 months. Let's see how much more time it will take. I think he is having trouble wearing the shoes. Shoes are definitely not made for him. The surface he is walking on is very plain and the speed is very normal. I have reduced the length of the walks, but I still think that shoes will be best for precaution.

They are saying that pads will be less irritating and dog's love them.
