worth the price !
Size: 5 Pack, Size: 5 Pack
Best toys for our livestock puppies since they have been getting into our outdoor things which isn’t their faults but i figure I would get these small squeaky animals toys and they are obsessed and love playing tug a war with them! They’re super soft, the quality is amazing cause these puppies are tough chew monsters, love the squeaky sound it makes and the patting are suitable as well! Definitely recommend this especially for the price and how fast shipping was !

Solid dog toys HOWEVER...
Size: 5 Pack
Got these toys for our collie-retriever. He loves them and plays with them a lot and will even get them out in the middle of the night to play with them. Since there's no stuffing you can't throw them very far but they are good for tug-of-war and really soft. The one downside, while they techically are durable and hold up to rigorous chewing, they are not impervious as our little man finally disembowled Mr. Lion after a few months of playing with him. (Serated the lining with his teeth.) Still highly recommend.

Not very durable
Size: 5 Pack
They’re a great toy for the dog. However, if the dog is bigger, they are very easily destroyed.

Hold up to a heeler!
Size: 5 Pack
I have a red heeler who destroys chew toys in quickly. I was extremely happy with these ones. They are made of thicker material and even after he chews the squeaky piece out, I can play tug of war with them without them ripping apart. The price for the quality is the best I have found in a long time.

My dog loves it
Color: 1 PC-Beef-Red, Color: 1 PC-Beef-Red
The bone arrived today and my dog loves it.
He is a very aggressive chewer and destroyed almost all his toys so far, even toys that were advertised for aggressive chewers unfortunately didn't held out long, the longest so far was a stuffy we couldn't find anymore and that one lasted him a few weeks but everything else lasted him an hour up to a few days max, even bones don't last him long so we have our hopes set on this bone to satisfy his chewing needs.
I will update my review later on sturdiness, since we just got it and I can't review that yet but so far he loves it he has been chewing on it non stop, he already managed to get very small pieces of as shown in picture but with a regular bone he would've already been much much further.
The bone is only 10 bucks so the value for money you get based on my experience so far is amazing! But also for this I will come back later to touch upon more.
The size is good, our boy is a medium sized dog and this bone was advertised for medium to large size dogs and I thinks the size is just right for our boy .
And there is definitely a beef flavor on it you can smell it but it doesn't smell bad it's a nice smell and not very strong but when he is chewing on it you smell it.
I would based on my experience so far definitely recommend this bone but also on this I will touch back upon later if it's worth it in the long run.
So far a very happy dog and owners here.
Edit on May 8th (original review was on March 11th)
He still hasn't managed to destroy it it's the first (cgew)toy he hasn't managed to destroy yet which is very impressive since he managed to destroy the even most toughest things we got for him in a week tops and bones within 1, 2 days tops, so we are very happy and pleased with this bone and will definitely get more later.
He still enjoys chewing on it and leaves our things mostly alone for some reason he just likes stealing my things and chew on it lol.
So 2 months later still stand by recommending this when your dog loves to chew and destroys everything he puts his mouth on.
