If the reason she is putting on more weight is of medical nature, then you should consider a treatment for it.
If she is a rescue dog and didn’t want to eat for a year, it could be that she is suffering from some stress 🙁
Also, how about searching for a dog food which contains similar ingredients as that one but with a lower amount of fat and calories in general?
If the increased weight is not a medical issue then you should exercise her much more, it could be that her metabolism needs some activity in order to start using that food she intakes. But I am afraid that the problem is medical..
If she has lack of appetite and can’t seem to control weight then that just speaks that something is off..
have your vet do the blood work too and check the hormone levels.
