Throwing Up After Eating Grass
There are conflicting theories about why dogs eat grass. Some say that a dog will purposefully ingest grasses to induce vomiting. Others say that a dog will ingest grass to receive needed nutrients and vomiting is just a bad reaction to that.
The best thing you can do is to prevent your puppy or dog from eating grass in the first place. This breed should never be left outside alone without supervision. Not only can the grass contain lawn care chemicals and insects, a Chi may ingest small pebbles that can cause blockage or eat poisonous weeds or flowers.
Feces on the grass can cause worms and other diseases and urine from wild animals can cause Leptospirosis (a disease not all pets receive vaccinations
With low ability to regulate body temperature, the possibility of finding an escape route and being vulnerable to dog-nappers and birds of prey such as hawks, the Chihuahua should always be kept on leash and watched when out in the yard.
With this said, if a Chihuahua still shows an urge to ingest grass - with or without vomiting - taking another look at his diet and making changes to a higher quality brand may be needed. Also, do not forget the importance of giving your dog a full and complete daily vitamin and mineral supplement.
When a Chihuahua has an acute attack of sudden, projectile vomiting this is a cause for concern. In many cases, this means that the dog eat a toxic substance.
Canines are super curious creatures and can get into places that you never thought possible. Not only can a puppy swallow a non-food object, he may ingest rotted food
from the trash, poisons liquids such as cleaning fluids or toxic foods that are safe for humans but can be fatal to dogs - especially toy breeds.
When a dog is vomiting due to poisoning, there may or may not be other symptoms. In some cases, the dog will look panicked and may turn in circles, pace or run around frantically, he may dry heave, become very anxious, shake, shiver, retreat or otherwise show signs of distress.
What to do -
It is always better to be safe than sorry and if your Chihuahua is vomiting violently it is best to bring him or her to the closest veterinarian or animal hospital without hesitation.
If you know what was ingested, bring the container with you if possible. Sometimes, a minute means all the difference and you will not want to take any chances.
Vomiting and Diarrhea
Sometimes a Chihuahua will suffer from both throwing up and having diarrhea at the same time and owners will be justifiably concerned. With very low body weight and limited bodily fluids, a Chihuahua can become dangerously dehydrated within just hours.
This can be caused by many of the same reasons as vomiting alone. This includes food intolerance, ingestion of a rotted food, ingesting poison, and the many possible diseases such as parvo and distemper.
What to do -
Do not give the dog any food at all and keep him on a liquid diet of water mixed with Pedialyte. The Chihuahua should not be left home alone; someone should remain with him at all times in case his condition worsens or if new symptoms appear.
After 24 hours, a small amount of bland food may be given to see how he does.
If there are any worsening symptoms such as bloody diarrhea or if the vomiting and diarrhea continues after 24 hours, this is reason to have the puppy
or dog look at by the vet right away. If the appointment is later in the day, continue to refrain from giving food and encourage him to drink water mixed with Pedialyte.
You may be asked to bring in a stool sample, so be prepared to collect some by flipping a clean plastic zipped sandwich bag inside out and then reversing it after the fecal matter is inside.
