Burns is a good food for helping dogs loose weight, you don't say what your feeding her at the moment, it could be that what your feeding is not helping the problem. Don't get suckered in by vets telling you that you have to buy diet food from them, that's a load of rubbish, it would more than likely be Hills which the vets get a kickback for selling.You can as someone else has said bulk her food out with veg, not many calories but it will make them feel full, you can also use veg as treats. You could buy a ball that you can put her ( dry ) food into that way she will need to work to get fed.
