I got Oscar from friends of mine down here who are breeders. He was 6 months old when we got him, he originally went to owners that left him locked up all day in a tiny yard and had developed a bit of an anxiety issue. The breeders bought him back and gave him to me.
The anxiety has been an ongoing issue, but he has simply the best temperament I've ever known for a dog. He crouches down on his belly to play with little dogs and small children. He learns quickly and is super willing to please.
As a breed they like to 'bring you things' This does include people who visit, they very gently grab hold of their arm and 'escort' them to you. This can be misinterpreted by people as 'biting', it isn't.
I've also had welsh springers which are the most loving and loyal dog, they call them the Velcro Dog. They are however possessive of their family and their families space so need careful training.
Growing up my best friend had an Airedale, quite simply, he was a magnificent beast. Very strong though but with careful training an absolutely wonderful family pet and very intimidating to undesirables.
