It is time to replace a dog toy when it's heavily chewed and can’t be effectively cleaned, torn or destroyed, with stuffing is falling out, or if it has pieces coming off that could be a choking hazard or be dangerous if swallowed. To maximise the lifespan of your dog’s toys, rotate them weekly, by making only a few available at a time. If your dog has a favourite toy, it’s best to leave it out for them to enjoy all the time.
