Finally a dental chew that my big guy doesn't swallow in 15 seconds.

The SmartMouth large dental chews are the best I've found for my large/x large dog. He immediately took to them and I think it's his favorite "treat". The chew is very hard and the sounds of the cracking alarmed me initially, but boy does he love it. Worth it? YES - Whiter & stronger teeth, hardened plaque disappearing quickly, and no more bad breath! To be fair I am also using some probiotics for the breath part, but it's the combo of the two that is showing clear results. Plus, it has joint supplements, great for my senior dog. I'm sold and love this product.

My dog loves these! They're hard enough that she can't devour them in seconds, but not so hard I have to worry about a chipped tooth. I feel good giving her a daily treat that offers teeth cleaning, joint health, digestive health and skin care that isn't full of a bunch of junk.

I have a hard time getting my picky husky mix to eat things consistently. I've been so pleased to see that she likes these, and she has started to expect them as part of our bedtime rituals. She's getting older and can use the extra support and nutrition these chews provide, it's a relief to find them all in one package instead of having to give her several supplements as we have been.

DRIED OUT

I was surprised for the price that these were a little too hard and dried out, I'm not sure if packaging was issue but won't reorder.
