Why should you buy a wooden dog chew? There are plenty of sticks and branches outside - for free! Chewing on tree bark and sticks is dangerous for your dogs due to bacteria, toxic trees, sharp splinters of wood causing dog gums, teeth and other health issues.WoofWood is made from coffee plants, 100% NATURAL, and FREE from caffeine, artificial ingredients, and additives. It?s 100% safe, non-toxic, and even safer than chewing real sticks. Real coffee wood will cause no allergy to your dogs. Being made from 20-year old coffee plants, WoofWood is tough, durable, and long-lasting. As your dog chews the WoofWood over time it flakes away releasing tiny fibres of wood. The dog saliva soaks into the wood and softens it up, so these tiny wood chips are not sharp and safe for your dogs' teeth, so there is no need to worry that it will interfere with your dog?s digestion, or cause choking. It is okay even if your dog eats these tiny fibers, please note many dog food manufacturers even add cellulose, a type of fiber to their products, as fiber facilitates proper digestion and colon health. The fine wood fibers also serve as a toothbrush. Although as with any chew, it is always recommended that full supervision is provided with ANY treat or chew. WoofWood comes in 3 sizes:Small (pack of 2): 5-inch stick for dogs up to 22 lbsMedium (pack of 1): 7-inch stick for dogs up to 44 lbsLarge (pack of 1): 8-inch stick for dogs above 44 lbs Safety Note: It is the responsibility of the pet owner to assess the suitability of any treat or toy. Always supervise your pet with chews and treats. Dispose of any smaller pieces that come loose to prevent the risk of choking. Ensure fresh, clean water is available at all times.
