This request for advice is from a disabled couple on facebook forum. They are looking for a puppy to train as a helping hand and seem to have their heart set on a cocker. They have contacted the place that trains these dogs but prefer to train it themselves. Don't know anything about how disabled they are, etc, but said I would ask.
They don't actually seem to be asking for advice, just if anyone has a puppy for sale they can buy (to their credit it is on the forum for health tested cockers)
