I tried Lulu on commercial raw food, and she just would not eat it. I gave up (I know that is disappointing to those who feed raw). I am feeding her canned Merrick which is a 5 star dog food on Dogfoodadvisor but none with chicken or rice because I don't know which one of those was making Lulu itch. Now for my question--when I was feeding Lulu my homemade chicken, rice, green beans, and carrots, she gained some weight. According to the calculator for her 5lbs 10ozs she should be eating around 180cal. a day. Depending on which canned food I feed her, they are around 1000-1100kcal per can and she should eat 1/2 can a day. She is losing weight. Am I not feeding her enough? Wouldn't that be between 500-550 cal. a day, and like I said she should be around 180 a day. Whay is she losing weight? I might not understand the calories on the can. Any help would be appreciated.
