I got mine at 10 months too and she was 5lb, and had the same issue. I ran around trying different kibble , givng her chicken etc. I fianlly realized somewhere down the line I became her personal sous chef! That had to change. (she also gained .75 lb being with us although the vet said that was good as she was underweight for her size.
So what I realized is that they are scent driven by food. So I picked the kibble I wanted her to have (royal canin calm)and realized it has no smell. So I boiled two bone in chicken breasts in just spring water, took the broth let it cool, skimmed the fat and put it in a bunch of ice cube trays. When its time for breakfast I melt one and pour it over her food. She gobbles the whole thing! I save the chicken for treats for good behavior.
She eats twice a day, 6am and 6pm. She gets a 1/4 cup for breakfast and a 1/4 cup for dinner. She inhales it. I now put water in it as she seems to developed an aversion to drinking from a bowl!
I also give her a mini organic carrot or two cut into long shreads or some organic romaine lettuce during the day. She also gets blue buffalo treats for good behavior. Hope that helps...
