Like most sighthounds, Whippets rather look down on training, but they can learn basic obedience and should be taught to walk on a harness and lead. Effort should be made to teaching them a good recall - although this shouldn’t be relied upon as the thrill of the chase can often mean their owner is temporarily forgotten.
If you own cats, finding a puppy from a breeder who has reared them with cats will help. If not, spend time teaching our puppy that the cat isn’t a chase toy. Whippets however may never be safe with other cats or small animals.
