Ruff and rugged
Color: Real Bacon&Beef
Ruff and rugged, my dogs chew through everything we get them, not this so far, holding up well against the aggressive chewers.

Has some flaws but overall not bad
Color: Coffe Wood
I have a 13 pound Jack Russell mix who is an aggressive chewer and gets bored while I am working. I find that a frozen treat situation keeps him busy for 30-45 minutes in his kennel so I can get some quiet time. I've been stuffing the Kong and freezing it, but since I only have one, I have to remember to do it. I liked the option of keeping a bunch of frozen treats to refill the toy at will. I've been eyeballing the Pupsicle brand, but they are really expensive. So for around $10, I figured this was worth a try.
Pros:
So far seems tough. I unscrew it after he finishes the frozen treat so he can lick out the remains, then I take it away from him. I'm sure if I let him he would eventually chew it to shreds.
The design is cute. Although you can't see the fact that the treats are brain shaped once it is in there, it does give me a kick to put a little brain in the skull.
So far no issues with screwing the top of the skull on or taking it off
The inner cavity is quite big. I filled the molds about 3/4 full and there is still a lot of room in the skull. If you have a bigger dog you can fill the molds to the top (just don't over-fill or it won't fit inside)
If you make a big batch of treat filling, you can freeze the rest in those silicone muffin molds, they fit perfectly. Just don't over-fill.
With a 3/4 full mold, made with pumpkin, peanut butter, oats, and a little water, it takes my dog about 45 minutes to get all of the treat out.
Cons:
It's huge and heavy. It's bigger than my dog's skull. But, since he is just trying to eat the brains, it's not like it needs to be lightweight.
The rope is a bad idea. First, it gets gross. Second, my dog has chewed halfway through it already. This seems like a hazard for both choking and bacterial contamination.
The biggest hole is big enough that my dog's bottom jaw gets a little stuck in there. So far he's always able to get it out, but it is a point against the toy.
Overall, its not bad. Not perfect, but serves the function. I'd like to see a slightly smaller, slightly lighter version for dogs under 20 pounds, and lose the rope.
If you do buy this, make sure to take it away from your dog once they have cleaned out the treat.

Great for aggressive chewers!
This item has held up for 4 months so far! My dog loves it, carries it everywhere. It's one of his favorite toys and he's been through so so many but this is the only one to hold up. However there are CONS! We have dubbed this bone "the cheese grater". My dog loves to bring his toys to us and press them against our legs to get our attention. So after a little chewing, the ends become very rough. When he runs by us with it in his mouth or presses it up against our legs, it tears our skin up! Also, the bone is very heavy so we have to watch out for our toes because Hank will drop it right on our feet if we aren't paying attention. Other than that, it's great! When it gets dirty, I just throw it in the dish washer and rinse it off after the cycle is done. Cleans up nicely! Would buy again if needed! Recommend for aggressive chewers!

This is the one for your dog
Size: Large
My 40 pound Mini Aussi is a very agressive chewer and goes through toys lightning fast===untill I got her this bone. She has had it several weeks and it still survives. She takes it everywhere she goes and it is, by far her favorite toy. I think she has met her match. One warning though. We have hardwood floors and it gets a bit noisy at times. That's just a small issue though. If Dixie ever destroys this (doubtful) I will not hesitate to buy another. Great toy and I coming off and she coming off and she wqw cfully recommend it. WARNING{ This is/was a great toy for my 50 pound Austrilian Sheperd, However it is not indestructable. It lasted about 3 months until the white parts started coming off and she was injesting it.
