    Great except for one small flaw
    Color: Regular - Beak, Color: Regular - Beak
    Our dog likes to get at the juicy innards of every toy we buy him. We tried this one as it promised to be "bullet proof". It lasted about a week which in fairness is 6.5 days longer than most of the toys we buy last. He ripped off the wings which was to be expected and not an issue. It took him another 6 days to finally locate a weak point and break in. It appears that the tag is not made of kevlar but merely sewed on. I guess it would be better if they had just sewed it on top but they made it part of the overall structural integrity. This provided a small area of weakness which our dog located and proceeded to exploit. It's like having the death star but installing a small thermal exhaust port that allows for access to the very core of the station. Makes little sense. Overall I am pleased with the overall sturdiness but in the end this toy had a small design flaw that my dog was able to locate and exploit in his neverending quest to gain access to and eat polyester fiber stuffing

    STRONG AS A MONSTER (albeit a cute one)
    Color: Large - Billy the Beast Monster, Color: Large - Billy the Beast Monster
    My aggressive chewer ate the adorable monster's ear off on the first day, but who cares? The body of the monster has been indestructible so far (one week). My 7 month old pup cbews it for a good 10-15 minutes at a time several times per day. Great quality product and outlasting all the other toys I bought (which she destroyed in 10 minutes - even the ones rated "Level 4 toughness" from Walmart. I think it's hilarious in my photo that the monster's expression perfectly shows his disappointment about missing an ear, LOL.

    King has met his match.
    Color: Large - Billy the Beast Monster
    I received my dog's toy this evening when I place the toy on the ground my dog King went crazy. He is a one-year-old Pitbull and love to tackle any toy he believes he can't take down, but Mr King has met his match with this toy. He was using all of his bite force to demolish the toy but the toy actually has worn him out. He ran around my yard for about 30 minutes with the toy in his mouth producing the squeaking sound from the toy as well. Hold up the toy is totally filthy with dirt almost covering the entire green and yellow belly of the toy. I have brought king mini toys in the last couple of months and this is the best toy that holds up to his energy level. I tried to retrieve the toy and place it in his dog house because it is far beyond his bedtime, but he wanted to play catch me if You can with my new toy. This is a great toy for those big energetic dogs that love to take their aggression out on maybe some furniture or perhaps that favorite shoe you do not want them to chew on. I am totally sold on this toy I brought from the seller who placed the items on the Amazon site. I plan on purchasing a another toy from the buyer to keep King energy at a low level if I can. I just checked on my dog and he actually has taken the toy with him inside of his dog house and now the toy is snugged under his left paw. I'm one of those smart owners I'm not going to even try to take it from him tonight but hopefully in the next week I can sneak it from him and it may be perhaps wash it. I did this item AA Plus

    Cute, but not Maligator-proof!
    Color: Small - Towering Timmy Monster, Color: Small - Towering Timmy Monster
    Fun toy while it lasts. My Belgian Malinois made quick work of this little guy but still enjoys playing with its carcass. Bite Force* but not taking into account the bite force of a Mali-gator!

    Puppy Love
    Color: Small - the Goofy Monster, Color: Small - the Goofy Monster
    Short backstory.... My daughter moved in with her 3 dogs recently and brought her dogs toys. Over the course of the last 3 months, my dogs have managed to steal every last toy they could find. fast forward to purchasing this Blue Monster. It came today and was immediately grabbed by one of my dogs. She refused to give it up even for her favorite ball. Ten minutes later another dog had the baby monster and was not giving it up!!!! (think growling) I thought that I would put the monster up for the night to allow for some sleep but it felt like it had been soaked in slobber ( I am sure I saw it drip ;) ). My dogs seems to think this little blue monster is their one true love. Now for some facts. 1. Baby monster is quite small in comparison to my other Bite Force dog toys. It is not too small for my dogs but it is definitely not a size I would give to my daughters Pit that thinks she is a vacuum. 2. Squeaker lasted about 2 minutes before my dog drool invaded it. Currently no squeaky sounds can be heard...just slightly squishy sounds 3. No holes despite my dogs trying. There has been constant chewing (by Standard Poodles) on this little guy for the last 5 hours and not one little open area. Trust me this is a huge accomplishment. Stuffies last 10 seconds in this house. If you need a toy that will last longer than most I highly recommend Bite Force. The are designed for tough chewers and take a beating
