19 pounds at 1 year old doesn't sound "fat" to me. Jax, a male, is only 6 months old and already weighs 25 pounds! I took him to the vet a couple weeks ago and he told me based on the food I was feeding him (Fromm Chicken A La Veg), he should be getting 1 1/2 cups per day. I had been feeding him 2 cups per day. I tried the Pork and Peas and Beef Frittata but he was constantly going at his paws and always itchy. I switched to the chicken as his previous food was chicken based and the itchiness has gone away.
