Acute vomiting will be one instance of throwing up that ends as quickly as it began and the dog acts perfectly fine afterward. Sometimes it will never be known what caused it and other times,
it may be a matter of the dog simply eating too fast one time or
ingesting grass
or even an insect that caused his body to react.
What to do -
1)
First, you'll want to watch your puppy or dog to see if any other signs appear. Look for dry heaving - this may occur if there is no food left in the stomach but there are still spasms that are causing retching. This can be very draining on a dog, zapping away his energy.
You'll also want to see if he appears to be in distress, is having trouble breathing, has weakness, refuses water and/or food or has any bloating.
Any of those signs can point to a serious problem and you'll want to take your dog to the vet right away.
2)
If your Chihuahua seems just fine after the episode, it is best to make the next meal one that is easy on the stomach. The above mentioned rice, oatmeal, bananas and/or sweet potato should do the trick.
You can mix the ingredients, for example plain oatmeal with small pieces of banana or rice with potato mixed in.
3)
Encourage your Chihuahua to drink and if there is reluctance offering an ice cube (plain or flavored) may work well.
Offering unflavored Pedialyte can quickly rehydrate a dog that has thrown up and revolve issue of weakness that may have occurred do to vomiting up fluids and food.
