It’s half the size of the last one that I purchased. It’s hard to tell from the pictures sometimes.
Should always check the dimensions of items because the pictures can mislead you sometimes
The bonus is a great product. It lasts a long time and it doesn’t break. I give this product five stars excellent but the size I purchased is for a smaller dog. Best Bone is what Wakanda growled.
Thanks everybody 🚀🇺🇸

A Humorous Twist on Tough Dog Toys!
Size: Large, Color: Lobster 3 Pack
I recently purchased the Nylabone Power Chew Dog Toy Pack for Aggressive Chewers from Amazon, and I must say, these toys have been a hilarious hit with my furry friend. As a dog parent of a strong and determined chewer, finding toys that can withstand their chewing prowess is a top priority, and these toys deliver both durability and a touch of humor.
The pack consists of three large/giant-sized toys in the shape of a lobster, cheese, and broccoli. The unique and amusing design puts a smile on my face every time I see my dog interacting with them. The unexpected twist brings a playful element to our daily playtime sessions, making it a fun and engaging experience for both of us.
When it comes to durability, these toys excel. My dog can be quite aggressive with their chewing, and I've struggled to find toys that can withstand their powerful jaws. However, the Nylabone Power Chew toys have proven to be impressively tough and durable. Despite rigorous chew sessions, these toys have remained intact, with no signs of wear or damage. They provide a reliable outlet for my dog's chewing instincts without the risk of shredding or ingesting any harmful materials.
The textured surfaces of these toys add an extra layer of interest for my dog. The ridges and raised bumps provide sensory stimulation, promoting healthy oral hygiene and helping to clean teeth and gums as they chew. I appreciate the added dental benefits these toys offer, as it helps maintain my dog's dental health while they engage in play.
I also appreciate the size options available in this pack. Large and giant-sized dogs often require bigger toys to accommodate their larger mouths and chewing strength. The included toys are appropriately sized for larger breeds, ensuring a comfortable grip and maximum enjoyment during play sessions.
As a bonus, these toys are made from high-quality, non-toxic materials, so I have peace of mind knowing that my dog can safely interact with them. Safety is a top priority for me, and Nylabone consistently delivers in that regard.
In conclusion, if you have an aggressive chewer and are in search of durable, funny, and engaging dog toys, the Nylabone Power Chew Dog Toy Pack is a fantastic choice. These toys provide hours of entertaining play, withstand even the most determined chewers, and offer dental benefits. Embrace the humorous twist and enjoy watching your furry friend engage in safe and engaging play with these fantastic toys.
Invest in the Nylabone Power Chew Dog Toy Pack today and let the lobsters, cheese, and broccoli bring laughter and durability to your dog's playtime!

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review!
My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.
