Using site calculator to determine calorie need for our Long Hair Chihuahua. She is a large bone size weighing 10 lbs and 4yrs old. We walk her daily but she seems to always want food. Concerned that she is overweight. How can we relate a human 1 mile walk to an equivalent mileage for her busy short legs as we walk? We are feeding her about 70 gms of Blue Adult Small Breed (Natural Fish and Brown Rice, Recipe small bits. We moisten 15-20 gms food with Chicken Broth. Serve 4-5 times daily. The way I calculate she gets about 350 k/cals daily. I guess it is slow going to reduce her weight to 8-9 lbs. Suggestions and/or encouragement appreciated.
