Coops $20 weekly fuel?? Shit you must be lucky to live close to a lot of tracks lol I go through about $100 fuel weekly just to trial, take dogs to mm, to races, go to petshop to buy kibble etc and to a meat supplier to get meat.
But for the average one dog yes Coops is about right.

Don't forget to factor in vet costs if anything happens to the dog, so always have an emergency fund on hand for unforeseen things happening, Mattstar.
