Not long lasting but my dog loves them
Flavor Name: Peanut Butter, Size: 20 Count (Pack of 1)
My little dog loves them. But they are NOT long lasting and definitely require supervision. Would love to find a product that would last longer than ten minutes,

Good Quality Chew for Dogs with Sensitive Stomachs
Flavor Name: Peanut Butter, Size: 40 Count (Pack of 1)
I have a small dog with a sensitive stomach and these sticks are perfect for him. It's a low calorie treat that takes him 10-15 minutes to eat and he really likes the peanut butter taste. These are not cheap but by purchasing them in the 40-pack box it's a little less expensive than the smaller 10 pack bags. I know there are cheaper brands for this type of chew stick, but I like that this product is made in the US and so I don't worry as much about poor manufacturing practices or unknown additives.

Great quality!
Great quality and ingredients. These are SAFE alternative to dangerous raw hide treats. My pups love these so much, they chew on them before bed every night. It's like a pacifier for them. It's a game for my husband and I to find their little stash spots in our bed. I've tried other brands and these are the only ones our pups will eat. I love that I don't have to worry about the safety of the ingredients. If you feed your dogs raw hide, I strongly recommend switching to these.

Great for aggressive chewers!
Size: Jumbo, Style: Peanut Butter
I have a very very aggressive chewer. She is a Rottweiler/Pitbull mix. Most toys she completely destroys within 2 days, sometimes 2 hours. I must praise this toy as she has had it for over 5 months and has not destroyed it! She loves chewing the ends and carries in her mouth squeaking it as she goes. I have 4 pups and they all take turns chewing when they can. I will be buying more Playology dog toys in the future. Thank you for making such a great toy!!

They are her favorites
Size: Medium (VALUE 2-Pack), Style: Beef, Size: Medium (VALUE 2-Pack), Style: Beef
We’ve had many dogs, many very destructive ones and wish I had these years ago. The hard toys get sharp edges, this toy is the best and yes is far better than the other red ones. My bulldog wants tug of war for 30 min to an hour every night. We’ve gotten tennis elbow, tendinitis, and pulled muscles holding onto this thing. She has tons of toys but 9pm and this is only option for her. We don’t get a choice. Easy to hold, well for a few min until your hand gets tired. First you one was about 3 years ago and she’s only on her third one. They last forever, easy to clean, and aren’t sharp edges. Seriously, better than any toy sold anywhere. My phone has hundred of pictures of Pickle holding this. She’s doing it right now. If you have a strong destructive dog that takes pride in destroying toys, ruin their confidence and get them this one.
