Hi Jane,
I was given a free bag of that (from memory around 5KG) when one of mine had a descale a few years ago - none of the dogs would touch it, offered as a "treat" :rolleyes:
IMO it is only the shape of the kibble which bears any relation to whether or not it
may assist in keeping teeth clean - but then again other manufacturers would have us believe their "dental treats" do this too. The simple fact is that if your dog chews it's food it will keep it's teeth clean and very few dogs actually "chew" dry complete food.
You could try using:-
Logic Gel, a non-brushing tooth gel which you apply with the finger along the gum line.
PlaqueOff, a powdered supplement added to the food
Fragaria, a homeopathic solution to plaque / tartar
Despite being a toy breed, your dog is still a dog - raw chicken wings (even just the tips) would help to prevent a build up as they require much more chewing, gnawing and crunching than commercial dog foods.
Hopefully something from the above will help :)
regards, Teri
