One aspect refers to the dog as a pleasant companion who lives in the house with the family. The second refers to earning obedience titles on one's dog through AKC or other kennel clubs. Almost every Clumber Spaniel makes an excellent household companion. Like most other breeds, the Clumber Spaniel puppy is a very rambunctious and destructive animal. He must somehow learn household manners.
Most owners prefer to take the dog to school for some outside help with obedience training.
One or two six to eight week courses will usually be sufficient to turn this dog into a companion one can live with. As in most endeavors, success will depend upon the amount of time and effort the human is willing to spend on training the dog. Each level involves about a year or more of very serious training. Or visit the AKC web site for more information. Go to an Obedience Trial and watch these different levels.
