First, my apologies for taking so long to respond. And second, thank you so much for all of the time and effort you put into the advice you gave me. I really did not expect you to give me such a wealth of information and it is appreciated. Few people take on this breed because of their size and the expense, etc, so there aren't alot of people out there who can give 'dane-specific' advice. I have been practising with Wyatt and his recall is improving thanks to increased effort on the part of his 'mommy' and the purchase of some freeze dried liver and duck and sweet potato treats. Yummers! I am looking more interesting to him by the minute! LOL I find that I have been getting better leash behaviour too. It's still a work in progress, but when I see him put himself in heel postion when we are crossing the street without my having to prompt him, I see that things are sinking in.
Unfortunately I am in Montreal so it would be a bit of a trek to get to your walks 🙁
But thank you SO MUCH for your time and help.
