Maybe feed a little less for the morning meal or whenever he is going to be left unattended for more than 4 hours. Two cups of food per day? I have a 20 pound dog that eats less…. How much does he weigh?

Some dogs eliminate 3 or 4 hours after they eat.

If your vet agrees I would try 1/2 cup of food for the morning meal.
Always have fresh water available 24/7.

Then in the evening take him out at least every 2 hours till bedtime.
