Tyson is almost 10 weeks old. I'm feeding him 1 cup Nutro puppy..large breed food, along with some wet puppy canned food and water mixed together 3 times a day. I feel him about 7 am. then again at noon, and then around 6:30 pm. I believe I am following the directions on the Nutro package on how much to feed him. But, I've noticed that he will spit up, not really a vomit, but like a burp that is juicy (kinda gross) and some stuff comes up. He'll do this sometimes HOURS after eating (today it was 5 hours after he had lunch.) Usually he has been playing and will do this. I'm not sure if I'm overfeeding...he eats all that is in his dish within 5-8 minutes...maybe he's a fast eater. Could he still be a little immature in his digestion? He also gets hiccups all the time...maybe 4-5- times a day. Silly boy. Any suggestions? I really appreciate your thoughts.
