Our Generation Happy Puppies. Teach your dolls how to care for younger pets with the Our Generation Happy Puppies pet care set! Clean your pups with the shampoo bottle and brush their soft fur with the hairbrush. Then dress your pup in the puppy diaper and lay down the blanket pad as you train them to go potty. Are they being a good pup? Give them a treat with the dog cookies as they learn! Place your pup in the zip-up dog carrier when it’s time to travel and carry them with the comfy straps. Or clip the leash to their collar to take them for a walk around the neighborhood. The leash can be made longer or shorter so your dolls can keep them by their side at all times!
