1. Starmark Pro-Training Clicker ($6)

Having trouble training your puppy? "For a nearly foolproof method of positive reinforcement, try a clicker training aid." First use treats as rewards for responding to the clicker, then use clicking instead of verbal praise. Buy it at Amazon.

2. SureFeed Small Dog & Cat Feeder ($143)

This automated feeder ensures that one pet won't eat another's food. The lid opens only when it detects an identifying microchip on the pet's collar or embedded under the skin. It closes as soon as the pet steps away. Buy it at Amazon.

3. Rocco & Roxie Stain & Odor Eliminator ($50)

This "professional-strength" carpet cleaner is expensive, "but there's nothing quite like it." The solution completely removes urine and other stains, using enzymatic bacteria that feed on organic matter. Buy it at Amazon.

4. Furminator De-shedding Tool ($29)

A Furminator is a wise investment as we enter shedding season. The fine-toothed combs remove the matted undercoats of short-haired or long-haired cats and dogs. Expect to be wowed by how much hair comes out. Buy it at Amazon.

5. Booster Bath Dog Grooming Center ($136)

This portable tub, available in three sizes, "takes all the stress and anxiety out of bathing." Its harness will hold a reluctant pet in place, and because the tub is elevated, you can do the whole job standing up. Buy it at Amazon.
