I wouldnt give a low fat kibble, Ive read that you just reduce the amount of food that ur giving them not cut down on their fat, especially if she is excercising & walking daily, if a normal fat kibble read for her weight to give say 4 cups a day, then u’d cut out about 1/4 to 1/2 a cup from her daily feed & see how her weight goes does she stay the same weight or gains or loses weight..If I cut out 1/4 a cup a day, I notice within 1-2 weeks my boy starts losing weight…when my boy was chattering his teeth he was cold..
