Built Safe. Built Tough. Let's Play!

It’s normal for puppies and dogs to chew on objects as they explore the world. Chewing accomplishes a number of things for a dog. For young dogs, it’s a way to relieve pain that might be caused by incoming teeth.

For older dogs, it’s nature’s way of keeping jaws strong and teeth clean. Chewing also combats boredom and can relieve mild anxiety or frustration. Dogs are diagnosed with destructive tendencies when they destroy things we don’t want them to, such as furniture, shoes, doors, or carpets.

Chewing is a perfectly normal behaviour for dogs of all ages. Both wild and domestic dogs spend hours chewing bones. This activity keeps their jaws strong and their teeth clean. Dogs love to chew on bones, sticks and just about anything else available. They chew for fun, they chew for stimulation, and they chew to relieve anxiety.

While chewing behaviour is normal, dogs sometimes direct their chewing behaviour toward inappropriate items. Not all destructive behaviour is the same, however. When a dog chews on the wrong things or digs in the wrong place but does not have any other symptoms, this is considered a primary destructive behaviour.

Dogs that have other symptoms like anxiety, fear, or aggression in combination with their destructive behaviour are diagnosed with secondary destructive behaviour. Both types of destructive behaviour can lead to problems with other organs, such as teeth, skin, the stomach, or intestines, if left untreated.

Both puppies and adult dogs should have a variety of appropriate and attractive indestructible dog toys. However, just providing the right things to chew isn’t enough to prevent inappropriate chewing. Dogs need to learn what is okay to chew and what is not. One of the best ways to prevent destruction in by providing your pets with enrichment items to keep them occupied. Give them strong, durable, non toxic toys to play with both interacting with you and when they are home alone.
