Hello. I'm a newbie here. I own a chihuahua for almost 2+ years if i remembered correctly. He's already 4 years old now. The only problem i'm having with him is that every time he eats too fast. He gobble up the kibbles sometimes without chewing and sometimes end up vomiting out because the food got stuck 'there'. I see he suffer so much every time something when wrong. Can anybody here please help him? Thanks..
