Thank you so much Willie for taking good care of our little boy. He now listens but kept his playful personality. I'm now able to take him outside to get our mail without me having to pick him up. Even though he is blind in his one eye, he is doing his best to heel right next to me. He used to nip on my toes, and since we got him this morning he's been a well behaved little pup. I think he's more funnier now than ever! :D This training is definitely worth it! We couldn't ask for more. Thanks again!
