I have been giving my Jack Russell these small chews for years. she loves them and they do seem to keep away the plaque. But they do not last very long. I often read the reviews to see what new comments are made and was persuaded by one of them to try the medium sized chews to see if they would last longer. Well - they were nothing like the small chews in form or content. In fact they looked just like squared off pieces of hide of some kind. And they were so tough that my little dog just couldn't 'eat' them at all. She tried over a whole week to make headway into the thing, but in the end I threw it away. So now I have a box of Medium Sized Logic Dental chews sitting begging on a shelf. I've gone back to the small size again. So, the experiment was a disaster; and I have no idea why the chews were so different. Goodness knows what the Large size look like!! I also would like to know why the small chews are the most expensive chews. The bottom line is that my dog likes them, and they seem to work on her plaque.

I have been giving these chews to my dog daily for the past couple of years. He loves them - end of day treat. They do a good job helping to keep teeth clean and breath fresh. But, as with comments in other reviews, there is an ongoing problem with the standardisation of sizing and thickness. My dog weighs 36kg and would benefit from the large but these are usually so big and thick he won't take them. So I give him the medium - but these are often so small and thin he needs two. Not a problem for him as he is always delighted to be given a second chew but I would be happier if there was more consistency with the product.

My Miniature Schnauzer has one of the small chews every evening, and have noticed that plaque doesn't build up no where near as quickly. The chews aren't at all messy either, which for a schnauzers beard is a massive plus! I must say though, she doesn't do much actual chewing on the stick, just chomps it up and swallows it. I'm wondering whether to try the medium to get her chewing more...

Both of my dogs seem to LOVE these & they seem to make a difference to their teeth. BUT... The chews are way too big - one of my dogs gives up after 5 minutes & the other one takes about 30 mins to finish it. Given that my dogs are staffordshire bull terriers with massive powerful jaws, this is very surprising & unusual for them. Because the chews are so big (& unevenly sized to boot) there are hardly any in a pack (I had less than 10). This makes them horrifically expensive if you intend to feed them everyday - for me it would work out about £40 per month!!! I would like the manufacturers to review the size & retail price as in the current size, I won't be buying an more.
