My sweetie is too! I've been able to see a visible difference since going to a "better" dry food instead of the easy canned dog food. Her vet is also happy to see the difference although less $$ for him! Ha! We use Iams, she eats less, more active and her coat is very shiney and visable weight loss as well & at 13+ years, very impressive! She still "expects" treats - that was one of the problems to being with, she trained us very well!
Bring her to the vet. They can do a simple blood test and first find out if she has a thyroid issue - which can be brought under control with a very inexpensive medicine. It may not be your dogs fault (or yours). If they determine nothing is wrong, they'll be able to advise you on how to address the issue.
