I have 2 cockers, both from Timsgarry lines.The 4 year old is a big (18kg) strong dog who will work all day and retrieve over land or water and pick up after a drive,Great for sending on to a lake to get the ducks up. His only fault is that he sometimes goes out to far from me when quartering- my fault as I let him do this over a period of time - but he always comes back on the whistle.My 10 month old dog has proven a bit easier to train as he watches me all the time.He quarters well and stops on the whistle at distance.Retrieving on dummies just started.Happy with both dogs - most faults are down to me - cannot blame the dogs.After 30 plus years of having Springers I am more than happy to have cockers working with me.Full of character and very happy dogs.You just have to keep on top of them.
