The guarantee does not apply to toys. If your TARIGS product shows normal (or abnormal) wear and tear from use, you may not qualify for our warranty replacement. However, we do offer product replacement for a fee. We do not guarantee or offer a replacement service for our toys, as toys mostly have to be chewed. We believe our toys are very durable, but some dogs chew harder than others. Products damaged while being used in an unintended way are not covered by the lifetime warranty.
