What is the fine-grained topic of the following text: By December 2011 we commenced feeding our adult Aussie dogs with the VAN - (Vets All Natural Complete Mix, which looks very like old fashioned muesli) initially we were mixing this with a Chicken and Vegie roll - the dogs did really well, their coats in particular became thicker and very glossy however one big thing was also the improvement in the droppings, especially how the poo no longer had such a strong smell nor did it have the colour and consistance of wet dry kibble - I suppose you have to think, what goes in one end does come out the other! Only return the topic.
