Our 7 month old lab has vomited 6 times in the past 6 hours. It is brown and looks like she's not digesting her food. It's not dark brown but the same color as her food which is the same she's been eating for several weeks. She ate some food in the evening and did drink a small amount of water 2 hours ago. She has had her shots to date. She chewed a ham bone day before yesterday. Was that bad to give her? When we walk her around the property she eats all kinds of things. We try to keep her from doing it but she eats grass, dog and cow poop, etc. Everything has to go in her mouth, it seems. It's after midnight here and we don't know what to do for her. Any suggestions?
