You may also notice a natural scent and oil while your pal chews; this natural oil may stain your furniture, carpeting or other surfaces. To prevent injury and choking hazard, please watch your pet while they enjoy this treat and be sure to choose the appropriate size chew. If this product splinters or develops sharp edges, throw it away immediately for your pet's safety.
