This is the best harness ever! Seriously, in the three days I have used it, Gracie and I are much more attuned to each other. I feel I have more control and so does she! Gracie is a rescue from a breeder (at 1.5 years) and is not yet sure how to be a dog (at 2 years).I highly recommend this for all English Bully owners. Our walks and relationship have been vastly improved. Gracie knows I am in control (gently) and seems so much happier and cooperative with this harness. Thank you!
