The sky's your limit really. :) My (and the dogs') current favourite is the 2 kilo packs that Natures Menu do of COOKED chicken cut into pieces. Each piece is about an inch so for smaller dogs it easily cuts into lots of pieces, they absolutely love it and a bag lasts for weeks and weeks and is kept in the freezer. Of course, you can buy chicken pieces in the supermarket as well, but it works out a lot more expensive.
Then you have sausages and hotdogs, again cut to size (assuming the dog likes it, I have two that don't like sausages), liver or liver cake. The only dog treats I use are Natures Menu ones that are 95 % meat, comes in various meats, again can easily be cut into smaller pieces as they are nice and soft. The one boring dog treats I use are B & M's own small dog training treats, a bag for 99 p with really tiny treats in (smallest I have ever seen), my son uses them when training his Papillon. But she's not picky, most of my dogs would not eat dog treats other than NM as they are too boring. :)
