Great for chew master

Keeps my 1 year rescue puppy busy for hours at a time. Has lasted over a month. I am grateful for this. Other tough toys were a joke- he would destroy them in minutes.  He really enjoys this. And hasn't been tempted to chew anything else in the house

My Havanese love these, but I use a clever and cut them in half to make it easier to chew.
Freshens breathe for awhile.

Chester thinks these are very yummy.  They give him a long chew time, which for Chester is great.  He is an aggressive chewer, and really works his toys:)

I buy the large alligators for my older dog, and I bought the sticks for my teething German shepherd/lab mix puppy. He only gets one per day, but it helps him chew and he loves the taste. I have recently had to upgrade to the medium size because he's getting bigger and getting his adult teeth, which helps him blow through the small ones in about 5 minutes. Make sure you get the appropriate size for your dog, and always supervise chewing.

My dog will chew on this even when it is dishwasher clean. He chews on it in various ways, which seems to help his gums get a massage. He isn't terribly hard on his chew toys so I can't speak to durability for those pets who tear through toys quickly.

My dogs love these chews. They get a job they love getting these chewed from the Kong. It keeps them focused & content for at least 20 minutes (I have labs) Great buy, I saved a substantial amount buying 8 at a time (2 per package). They both get one every Friday, that's a 2-month supply that I would not otherwise be able to afford. Thanks for such a great deal.

I have a super-chewer and this has lasted a week already. He's been happy to chew the mint flavor alone (nothing added in the holes), so that's impressive as well.

We got Jackson, a shelter dog, some of these along with an assortment of other brands, and these are his favorites.  They last a long time and I have one in each room so he avoids chewing anything other than his toy, works out great and he's a happy boy.  He is a Corgi mix, about 25 lbs. these bones are easy for him to hold and chew.

My 4 month old pup loves these and I like giving them to her knowing that they won't cause digestion issues. I know she's still pretty young but she's a pretty vigorous chewer and will work away at this for 15 mins at a time. The xlrg one I got her has lasted for a month now and still isn't through. I'd highly recommend trying these if your pup gets the runs after bully stix or other chews as this is more flavorful than antlers or raw bones alone but less harsh on the tummy.

My dog pretty much eventually chews up everything EXCEPT the hard Nylabones ... she has three including this one. They keep her interested and are great for dental health. She'll destroy one of the soft dental chews in less than a day, but these are every-lasting.

This one is her favorite: she loves to "plant" the 2-pronged side in her blanket and just goes to town on it.

I recommend all hard Nylabone products.

These are also great - since these are all I'll spend any kind of money on anymore, I try to give her a variety:

Great, as per usual. Nylabones are the best for our hard-chewing pit bull...he sometimes works on them for hours at a time, but it's still there! They last a long time and are very worth the money.

My 50 pound pup Sigma adores this toy. It is his favorite ever and he will neglect his other chewies when this is around. It handles his vicious chewing well. While it does get a little prickly, most toys do and it doesn't deter him at all. He hasn't managed to get any big pieces, just small scrapings. I recommend this toy enthusiastically for any obsessive chewers with the caution to watch the little bits of plastic.

My dog, Bailey, loves these dental chews.  I have broken them in half and thirds, as Bailey has a sensitive tummy, but she handles the Perio Plus chews very well.  They are crunchy on the outside and soft filling.  I highly recommend them.  They have helped keep Bailey's gums and teeth in good condition, and she is 12 years old.

Dog loves these. I no longer give bully sticks since they go so quickly and are too rich (stomach upset). These are good solid chews that my dog loves and the price/value is great. I have had no issues feeding these to my 60-65 lb goldendoodle who chews all chews very fast. Like I mentioned, no stomach upset or choking so far.

No issues, my 5 month old 35lb Golden loves it, he is still teething and this is perfect for all the chewing he has been doing. I believe three will last us a little over a month but keep in mind my teething pup chews on this for several hours a day. Better this bone than my oak table. I would purchase again and recommend for any dog between 25 and 60lbs. .

2nd purchase July so three for a 40lbs give or take dog lasted a little over a month for me. My dog is now 7 months old and 59 lbs, I went with the medium again mainly due to price and shipping cost on the larger ones. He chewed on it last night for 3 plus hours and 1 end piece is now gone. I believe that three of these will last my Golden 3 to 4 weeks. I will order again, maybe try the large next.

These compressed chews are so much better for you dog, especially smaller dogs or puppies. My trainer recommended to me and they were a life saver. They last much longer than the regular rawhide bones

These chews have really helped with her bad breath! They help kill the bacteria (I'm guessing) and remove plaque (with enzymes). I give her 1 or 2 a day, and she absolutely loves them. She can chew through one pretty fast. They are about 5 to 6 inches long and range from thin and crispy to thicker and more hard (all inside the same bag). I like the variety, and I think my dog does as well. They don't stain the carpet (I have almost white carpet). I recommend these over regular bones as a treat because the enzymes inside the bone really help dogs with their teeth, and do not just cover up bad breath with a "doggie mint" I always like to supervise my dog when she is chewing a bone - give them to your dog when you are watching TV so or reading so you can keep an eye on your dog. Have fun :)
