**** Important message****
For those who are interested in getting your dog a puzzle toy....according to the company's advice, it has to be supervised, do not just leave it for your dog to play as there's a possibility that your dog might chew and swallow the hard plastic which will cause major issues....They are hard plastic, they can do a lot of damage to their intestines etc.....!!!
