Approx. 3-5 times a month my dog gets sick in the early morning 3-6am. He has no other issues. Energy is good, acts normal, poop is normal. He wants to eat on his schedule even after getting sick. He only eats dog food, no people food.
His vomit is usually clear stomach fluid. I don't see him eat any plants or other garbage.
He is not sick any other time in the day.
Any thoughts???
