Looks Nice But Destroyed by my Lab
Color: Checkers - Elephant (Gray), Size: Large, Color: Checkers - Elephant (Gray), Size: Large
A really cute little elephant. My lab loved it and carried it around for a week. Then the elephant began losing body parts. Both legs are gone now plus the big squeaker. Lab still likes the elephant and carries it around. Its loosing stuffing and the real question is what body part is next. Its nice but not tough.

Still in one piece and played with!
Color: Checkers - Dinos Bruto (Purple), Size: Mini
Very durable for my little King Charles Chewer. She's had it for a while now and all though the chewing phase has calmed down, she still can be somewhat rough with the toys. The little dino is standing firm. It was a battle she figured she couldn't win with Dino. Now he's a fetch/ tug o war toy that still gets a few nibbles.

DONT BUY THE ELEPHANT, ITS NO GOOD. but GR8 BRAND!
Color: Checkers - Elephant (Gray), Size: Large
The elephant toy had no trunk by the FIRST day! The elephant now looks like an angry Koala bear OR an angry trunk less elephant(whichever u want to say) I LOVE the donkey and dinosaur toys so I bought the elephant confidently, thinking I had nothing to worry about. I wouldn't have spent money on this knowing the trunk would be chewed off in a matter of minutes. My Bella usually chews but she has had her donkey and dinosaurs with the chew guard for MONTHS and there are NO TEARS OR RIPS even with her playing and chewing on them ROUGHLY all day. If you buy any of these type toys I DO highly recommend the donkey or dinosaurs ONLY. The elephant being chewed up in a matter of minutes really makes me angry that I ever spent the money on it. HAD I known it wouldn't be the high quality dog toy I'm used to from GoDog, I would've just bought a second donkey or dino! Now Bella doesn't get her new toy for the month (I try 2 buy her a new stuffed toy or 2 about 1 time a month whenever I have the extra money for it) I guess she will have to go without this month because I spent it on this now trunkless elephant/angry koala:( Whichever name you call it, it is now going to be trash. UPDATE! If you contact the GODOG company they will send one replacement toy for your pet! They also asked me my pet's size, breed and age in order to send the best possible toy! They sent Bella a snake that has held up Extremely WELL! It's great and so far is my favorite(and one of Bella's favorites) The snake has less sqeaky things in it so she doesn't have the drsire to tear it apart immediately to retrieve them by rippong it to shreds:) My updated rating is for the MANUFACTURER'S GREAT CUSTOMER SERVICE. The fact that they actually replaced it was good but the fact that they went that extra mile by researching the best toy match for my Bella was above and beyond! If you have a Godog toy that went bust right away, contact the manufacturer for a replacement. If you give them your dog's age, weight and breed they will even try to match your pets replacement toy with something that is better suited to your dog's chewing style. (Bella's style is destructive haha) Good luck, ya'll!

My Dobermans favorite toy to destroy, and one of our recommended picks.
Color: Checkers - Elephant (Gray), Size: Large
Ok, here's an honest breakdown review. I have a 6 month old Doberman who shreds every stuffed animal and dog bed he's come across. He's one of the worst chewers I've owned. We have tried a WIDE variety of stuffed toys. That said, this elephant is his favorite toy. I have ordered 4 of them so far, and just ordered another 4-pack on a buy three get one free deal. The elephant stands out above all the other stuffed creatures from goDog for me as to durability. Hence why I keep buying more. But they usually last about 2-3 weeks on average. In our house, the poor creatures are subjected to vicious, crazy, shaking of the head, helicopter type rotation. It' so hard if it hits your bare arm or leg it actually stings especially when its wet. Then the old, put it between his legs laying down, tearing at the legs action. The limbs are usually the first things to go over time. But they are each almost self sealing, so you clean up as little fluff and keep using it. Eventually the pup reaches the main body and finishes it off. For a normal light to normal chewer, one of two will get you a long way. For those of us resigned to having zoomie type manic chewers that need a constant supply of toys, 2-3 week durability is pretty sound too. I do not recommend the green cheaper monster. It lasted about 45 minutes. The free replacement took about 3 days. Hopefully this aids you in your decision!
