Chester has been on Eagle Pack Giant Breed Puppy since I switched him from ProPlan about two months ago. He's a seven month old Newf and he weighs about 75 pounds but he seems to be eating less and less. He used to eat about 2 1/2 - 3 cups of kibble twice a day with some of the juices from Cowboy's cooked meat and veg and about a 1/4 cup of Cowboy's meat mixed with his kibble. He's leaving more and more of his food in his bowl. I cut the kibble to a little less than 2 cups twice a day and he's still leaving anywhere from a 1/2 cup to a full cup in his bowl. He seems to be full of energy and ready to play at any time so I don't think he's sick....except he will throw up bile early in the morning (like maybe 4:30 - 5:00 (before my eyes are open!) but he's cleaned it up by the time we roll out (about 5:30). That's happend a couple of times....but not all the time. Do you think I need to change his food again? Any suggestions? I asked the breeder about it and he says that male Newfs are self regulating and will only eat until they aren't hungry anymore, but I don't remember my previous male Newfs doing that.
