So, what’s the difference between a Tuffy Ultimate Toy and a Mega Toy? Both are Tuffy Toy Tuff, the toughest soft toy with a squeaker. The Mega Toy has 7 layers of fabric, versus 4 layers in the Ultimate. This gives the Mega one more point on the “Chomper” Scale, so Megas rate a 10 versus a 9 for the Ultimate. Probably 90% of dogs can’t kill an Ultimate Tuffy Toy but, for those last 10% of chewers, grab a Mega Toy!
