Jack will only eat a tiny bit in the morning, maybe 2 or 3 bites, and usually I have to coax him into it with a treat on top. Then he won't eat until I come home from work, and then he scarfs it down, no treats needed. Sometimes he acts like he is hungry later, so I will feed him a second time at night. Sometimes I wonder if that is okay.
The only reason I might see it could be a problem is the second evening meal might be why he doesn't eat breakfast and why he scarfs down his evening meal.
