Treatment methods for a Gordon Setter that vomits after eating too much:

1. Don’t feed anything to the Gordon Setter for the time being, and let the Gordon Setter vomit. The dog's stomach is empty for a while.

2. If your dog shows signs of dehydration after vomiting, you should give it more warm water to replenish it.

3. Dogs can be fed some pet-specific probiotics appropriately. If the dog is less than five kilograms, feed half a bag, and if the dog is more than five kilograms, feed one bag, once or twice a day.

Causes of dog vomiting:

1. It may be that the dog ate too much food at one time, or vomited due to eating too quickly.

2. The dog may be infected with parasites. When the dog is infected with parasites, there may be parasites in the vomit.

3. Possible food poisoning. Food poisoning mainly refers to dogs eating poisonous food or food that has expired, spoiled, unclean, or been contaminated by germs. It will also cause severe vomiting in dogs.

4. The dog’s gastrointestinal tract cannot be irritated. For example, eating spicy, greasy, cold food, or catching a cold in the stomach will also cause vomiting.
