My first reaction was that these people don't seem to have the time to put into owning a dog. And their expectation that a dog will come 'ready made' to suit their wishes & wants is unrealistic.
Maybe they should speak to an experienced person at a dog shelter who could ask them the kinds of questions Karen has suggested...& counsel them about what is involved with responsible, caring dog ownership. Then the shelter person might suggest a dog that might match their situation.
