Piper will be two in September and for roughly a year has eaten two and a half cups of dog food per day, divided between am and pm. This last month she has been going to the pantry (indicating she's hungry I believe because she's never done this before) and I have upped her "scoopage" to two HEAPING cups but she still seems hungry. She doesn't appear to be losing or gaining weight and I was just wondering if your labs had an increase in appetite around this age?
