Great product

We have been using a number of Ark Natural products and our 16yo Beagle/Lab for years and she is still very active.

Good treats

I bought these for my 2 8 year old boys. They are little soft nibbles. They both really like them. I have noticed that my yorkie has been much friskier and playful. He must be feeling better! I only gave 4 stars because the bag is quite small for the price.

way too small

Pieces are minute. I feel the packaging was not indicative of the minute size. My labs and mastiff needed a handful.

Great Senior supplement

I started using this Ark Naturals supplement for our senior dogs last year, originally buying it through Swanson's Vitamins, but Chewy does offer them at a slightly lower price, which is sweet, and now with auto shipping, it's become more convenient for ordering and won't run out before getting them ordered and delivered again.

Old Bones Chews

She hasn’t been on them long enough to see if they make a difference, but she is so picky about how her medications are administered. So many of the other ‘treats’ she has refused. So far, she seems to like these, so money not wasted, at least so far.

Dog won't eat these treats.

Gave my dog 2 of the treats. He ate one and refuses to eat any more.

So disappointed--no longer "soft and chewy"

I have been buying these treats for over a year for my little old dog that has no teeth. Suddenly they are no longer soft and chewy as stated on the package, but rather solid and crumbly. I asked the company about it and they said they'd changed the recipe. Boo.

Nice little treat!

My dog seems to like these, but hasn't finished a bag just yet. I hope to see some improvement!

Fantastic product

My older girl was limping badly from arthritis. She required pain medication. I saw these and decided to try them after reading the ingredients, and they're made in the USA. She rarely ever limps now AND she runs ! She has also returned to slaying her toys.

My dog loves these treats!

My lab is a pretty picky eater. She will chase me around the kitchen to get these treats in the morning. The treats had good online reviews. I wish I could ask my dog if they make her feel better. But the one thing I do know for sure is that she really likes them.
