Sounds good Susanne. I might try it when the dental kibble used up which will be a while yet as only really use it for treats. At £15 a bag, I ain't chucking it out (and they all love it and both Tom and Billy crunch it about 4 or 5 times before swallowing). Where do you get the Plaque Off from and how much does it set you back? Thankfully, apart from Freddie with no teeth to speak of, other 2 seem OK (touch wood) and no bad breath probs. Would do no harm tho to try and ensure no future probs.
