Terrible, my galgo ripped it to shreds within a couple of minutes. Definitely not "hours of interactive fun" here! Waste of money.
Excellent highly durable toy. Have had one for 3years and it's still 'alive'. Just bought another for a friend with a Staffordshire Bull Terrier because I know they last.
One of the best dog toys, my dogs simply loves, and it lastes a long time.
