Most food manufacturers seem to quote far beyond the real amount a dog needs - my boy is on just over half the recommended amount of JWB! Check how much the breed standard says your dog should weigh (or take the average if she's a crossbreed, you don't say!) and weigh her to see how close she is to what she should be, then adjust the diet as needed and check the weight regularly. :-)
