At first the SmartMouth chew was too hard for my dog but now she loves them.

I love the 7 in 1 dental chews from Smartmouth, because they check off so many boxes and are easy maintenance for my dog's teeth. At first, she would intentionally drop the dental chew out of her mouth without even trying to chew it and it seemed too hard for her. They are definitely much harder than any other dental chew we have tried. My large dog loved his Smartmouth chews, and after seeing his excitement every time he got one, my medium sized dog decided she should give it another try. Now she jumps with joy when she sees the "treat" and clearly enjoys chewing away on this dental "bone." There have been no side effects, except whiter teeth and better breath for both my dogs! If at first ya don't succeed, these are worth trying again.

I've noticed that Chewy's products are never expired but wherever they store the products can cause the items to harden. The chews were so hard I was afraid my dog would chip a tooth. I will buy from the Missing Link website from now on. Other than that, it's a good product.

My 50lb, 2yo dog had a VERY hard time with these (I got the medium size). It sounded like she was chewing rocks! These are rock solid and cannot be broken... they don't seem safe for teeth(especially senior or small dogs). I love Missing Link brand but these were a miss. Maybe I got a bad batch?!

Too hard!

I tried Because I was cutting down on my dog calories and I could not. If I can't cut them in half, how can they be safe for my dog's teeth.

Teeth look AWESOME!

A year ago my vet said I needed to have teeth cleaning done on all 3 of my dogs. They are 8, 9, & 10 years old. I didn't want to anesthetize them for the procedure

A year ago my vet said I needed to have teeth cleaning done on all 3 of my dogs. They are 8, 9, & 10 years old. I didn't want to anesthetize them for the procedure. They get this every night before bed. My vet noticed how good their teeth look & asked if we were brushing them. Our 120 lb Labrador gets the big ones. All 3 dogs refuse to go to bed until they get these. AMAZING!!! I have used Missing Link powdered supplements for over 10 years & reccommend

My Pug, like most, has bad teeth. I’ve tried other daily chews but she eats them in two seconds because of how soft they are. These are hard enough that she actually has to chew at them for a couple minutes but not so hard that she can’t eat them (she is a Pug after all).
