Cockers are very much people dogs. but any dog must learn to be left on it's own for short periods, everyone needs to go shopping, run down the bank, and now and again go out for a meal (though we can't do that often!)
Some people will say different colours have different temperments, others will say they are all the same but its the lines.
Re working and show lines. For working a dog will be finer, less coat and possibly more working instink and seem leggier. The show type will have more bone, coat and be over all more "showy" Although you might argue they shouldn't be a difference, face the truth and there is! Like any gundog she will need alot of attention and exercise, and I would say any dog needs at least 2 walks a day.
They will also love any attention you give them from my experiance. But be careful where you get a puppy from, make sure you get one from a good breeder, with health tested stock.
