Can't really say. I own sighthounds, and commiserate with people who own sighthounds, thus I must enjoy a challenge!

But I used to work fir a groomer. So I have to say that among our "regulars" I think it was a standard Poodle that was the best trained. And a real sweetheart!

He never needed a lead; we'd just tell him what we wanted him to do, and he'd do it. Grooming table? no problem. Bathtub? no problem (needed help getting in, though - it was tall!). He was cool. Liked to play games too. He would often smile at me, and offer me a paw, just so I'd come over and he could lick me! It was rather entertaining!
