There are various factors that will cause vomiting in dogs. Sometimes it may be a result of a medical condition such as colitis or kidney disease--other times it may be the pet has a food allergy--or simply put her mouth where it didn't belong. Here are some ways to control vomiting.
Instructions
Feed at least two meals a day. Most dogs, especially smaller dogs, do better with more than one meal. Just like humans, once a day isn't enough and can cause nausea, which in turn can cause vomiting.
Don't allow your dog to drink a lot of water at once, especially before a meal or after coming in from the heat. Pick the bowl up before he drinks too much.
Don't let your dog run or engage in vigorous play for at least an hour after a meal.
Try to walk your dog during cooler weather, and if it's summertime, in the early morning or evening hours is best. Hot weather can sometimes cause a dog to vomit, especially on an empty stomach.
If your dog vomits more than once or twice in a day and it continues, feed a bland diet. Start off with white rice and mix in a couple of tbsp. of cottage cheese for the first day or two. You can also add a tsp. or two of canned pumpkin, which helps control vomiting. If your dog won't eat this meal, you can throw in some ground beef (but make sure to rinse it after cooking to get rid of the fat). You can also use low-fat chicken or turkey, but ground beef is actually softer on digestion. Continue with the rice, cottage cheese and beef (or chicken/turkey) for a few days to keep the vomiting under control. After a few days gradually wean your dog off of this food by mixing it in with her regular food.
If your dog is prone to vomiting it could be from food allergies. Feed a sensitive stomach formula dog food or one with no grain, which can often cause food allergies, and thus vomiting. Dick Van Patten's Natural Balance limited ingredient, allergy-formula line consists of only one protein source (meat) and one carb source (potato or brown rice), which decreases the chances of an allergic reaction.
