Does he have the right food? With suitable, I mean, whether he can eat the food at all reasonably? Chihuahuas are tiny and have small jaws. If the food is too big and too hard, your Chihuahua may not be able to bite and eat the food properly.

Nutrient deficiency

Your Chihuahua may be eating enough, but not enough is getting there. Ensure you’re feeding high-quality dog food and providing your Chihuahua with all the nutrients he needs.

If you have cheap dog food packed with cheap fillers, your Chihuahua is not getting enough nutrients he needs for a healthy body.

Various diseases can be the cause of why your Chihuahua eats less and is so thin.

Dental diseases, for example, could be why your Chihuahua eats poorly and loses weight.

A visit to your vet can help.


Stress is a common reason your Chihuahua is not eating and getting thinner. Your Chi can be stressed for a variety of reasons. Is your Chihuahua getting enough exercise and activity?

Worm infestation

If your Chihuahua loses a little weight in the short term, this is no reason to worry. However, if your Chihuahua remains underweight due to malnutrition, the following problems can occur:

  • weakened immune system and therefore more susceptible to diseases
  • poorer recovery from illnesses
  • disturbed hormone balance
  • shorter life expectancy

Avoid that your Chihuahua becomes too thin.

Feed your Chihuahua twice a day. Preferably in the morning and evening with high-quality food that provides him optimally with all nutrients.

Do not give treats for the time being. If your Chihuahua gets two or three treats, he will usually be almost complete. But treats do not provide the nutrients a dog needs; they are more like sweets.

Avoid stress as much as possible. Make sure your Chihuahua gets enough exercise. Then your Chihuahua will be hungry and eat his food.

If nothing helps, try other food. Just because your Chihuahua does not eat his current food does not mean that he does not like any food.
