Nice dog toys
Color: 25 Pack (Value-Toys)
Nice toys, but no match for my 2 year old female pitbull. Most toys she shreds. Even some that are supposed to be indestructible. Some of these lasted for a while.

Great and solid chew toy for those "eager" chewers!
Color: Blue Shark, Size: Medium, Color: Blue Shark, Size: Medium
This is a winner! Especially if your dog is an aggressive chewer. My dog is a 30 lb on the outside but on the inside is a 200 lb tiger/bear who likes to gnaw/destroy everything.
I only wish I were joking. We've had this little toy for however long now and she goes to town on it and I don't have to worry like I do with other toys. Because no pieces are falling off or breaking off and she's a happy camper. And I'm a happy camper because I'm not all up in her gnawing business.
As you see in the picture this is the perfect size for her. I think she is a mini aussiedoodle but she's approximately 30 to 33 lb of pure energy, love, sloppy kisses, and aggressive chewing.
Best toy has its me money by not having to replace more shoes and chargers of all sizes. I think it's kind of cute and she is very protective of it. As I was taking pictures to post, she came to me, got it, trotted off, and you see the end results: her with the toy, protectively holding on to it.
She loves this thing and I'm about to order another one just to have just in case. I will mention it is heavy for its size. But unless you want to knock somebody out, I wouldn't recommend throwing it. At all.
I don't think any dog smaller than her could carry it around and I don't have a scale to weigh it but this is the perfect size for her.
This truly was the best chew toy I have gotten her in about a year, and I am not exaggerating.
We are huge fans!!!

good toy for heavy chewers
Color: Blue Shark, Size: Medium
My dog loves this toy. It is tough and has a nice squeak. The only thing that bothers me a bit (it doesn't bother the dog) is the plastic tail gets rough with the chewing.

Just buy it!!!!
Color: Blue Shark, Size: Medium, Color: Blue Shark, Size: Medium
5 stars so far! My beefy boy is obsessed with this toy. He’s a TOUGH chewer. It fits perfectly in his mouth and it’s definitely tough! Feels thick & sturdy, has no weird smell. He loves the squeaker and he’s been (trying) to tear it up non stop since I gave it to him! Lol. He wore himself out. Definitely ordering more. Love the different animals !

Durable and fun toy
Color: Blue Shark, Size: Medium
My granddog really likes this toy. He is a pit bull mix. The middle is where the squeaker is. Toy is hard plastic and he chewed on it a long time. No damage to toy! The only reason I gave it a 4 and not a 5 is how loud it is bouncing on wood floors. The toy I do recommend. Good size and bright blue color fish.
