It is hard to fit an Australian Shepherd with most harnesses. If they fit around the middle, they are too large in the chest. The Wonder Walker is totally adjustable for your dog. I loved mine so much, my husband bought one for his dog.

harness and customer service first rate. I mentioned it was for a rescue friend and they offered to make a donation to the rescue. support local companies/businesses!

We exclusively purchase Wonder Walker no pull harnesses, as our trainer recommended them, and they've proven to be a great harness for our golden retriever puppy.

Straps are larger than Halti

Well constructed and effective against pulling. Great product!
