Chewing is a necessary activity for all dogs - not just puppies.
Chewing keeps a dog's jaw muscles in good shape and also helps to keep their teeth clean.
Stuffed chew toys, like Kongs, offer the added benefit of supplying both mental and physical stimulation.

When choosing a dog to add to your family, please do a little homework first. Different types of dogs have different requirements – a dog isn’t “just a dog!” If you live a very sedentary lifestyle, you might not want to choose a high energy breed that requires a lot of exercise, even though you think they’re beautiful. If you’re a neat freak, the really heavy shedders and droolers might not be for you. Typically, the larger the dog, the more it costs in food and vet bills. Take everything into account before making your decision. I can assure you that it’s worth it, because there’s nothing sweeter than finding the “perfect” dog for you.
