Just wondering if changes in appetite is normal for pups? Peanut is 4 months old. The last week and a half, his appetite was poor. He stopped eating as much as he normally would. I measure each feeding, so I know pretty well what he eats during a 24-hour period. His intake was cut by more than half. Now the last couple of days, he's wolfing down food like nobody's business. Is this normal? I was beginning to think last week that maybe it was time to cut down his feedings to twice per day, instead of 3, but now he eats like he's starving every time I feed him.
