Farley is gorgeous, absolutely! I agree with most of the advice posted here, some good stuff... I would just add that someone said that working Dogs need to be 'doing stuff,' excercise is more important for them than most Dogs, and that is very true. Good advice. Training should be done, as was implied too, after excercise.
As for chewing up the sofa, or whatever, lol. I can honestly say that I haven't had a Dog chew anything that it shouldn't have chewn. Plently of Doggie chews, toys and excercise will take care of any desire to destroy. My three have never done so, nor have other dogs I've had in the past.
Of course, they all have their idiosyncracies, and one of mine, when she was a Puppy would worry me to distraction by 'collecting' pebbles, small pebbles that she found around the house. I was very afraid she would swallow one, altho she never did; and of course, it was just a phase that she went thro.
She would also bring into the house every single leaf that she found blowing in the wind (I swear her Sire, or Dam was a Cat), and that the breeder conned me, lol.
I think it was muleman that said that they are like children/toddlers? In any event, that is so very true, and just like children they each have their own individual personalities, and whilst its wise to remember that they are not children, or toddlers, one does need to treat them as such when training them. Some Dogs become distracted very easily, as do some children. They need endless patience.
Personally I never, ever give any of my Dogs human food (and they are rarely ill, if ever, and rarely need a visit to the Vet). I'm convinced that that is the reason why. They get Doggy treats, but never, ever for doing something that I am training them to do, and never for what I expect them to do. I want them to do those things because they must, not for reward.
Boundaries are essential, and treats are for when they are relaxing, or at the end of the day when they have been good, or patient, ie; because I have not been able to give them the time that I should, or just because they have been especially good.
Farley sounds to be a very lucky Dog to have gotten a good home, with people who will love him, and treat him as he deserves to be treated.
