Is it common for a Chihuahua to have bottom teeth showing? Is this an anomaly I should be concerned about? Many chihuahua owners are concerned when their puppies start to present this type of malformation. In this post we are going to talk about the prognathism of chihuahua dogs and in addition we are going to talk a little about the physical characteristics of this breed.
Chihuahua underbite
Chihuahua dogs may present a probability of the occurrence of the projection of the mandible; however, this projection cannot be so visible. In a few animals’ excess growth of the mandible can be observed.
This type of formation where there is an excess growth of the lower part of the mouth, in relation to the maxilla, located in the upper arcade is called prognathism.
The Chihuahua breed dogs can be eliminated from breed competition and even be penalized for having prognathism. Therefore, the selection of animals that present an almost imperceptible prognathism is desired.
Prognathism is an anomaly that does not change the life of the animal, it is generally considered more of a visual / aesthetic anomaly. Because the animal can live a normal life.
In more severe cases of prognathism, the dog’s mouth may be a little open and with this the animal may salivate more than too much, in addition to presenting a little difficulty in chewing.
Treatment for prognathism in dogs is not indicated, and therefore the tutor must be adapted to offer maximum comfort and quality of life to your animal.
About the Chihuahua breed

Breed health
Chihuahuas are very healthy animals, but they need to do physical activities such as playing and going for walks to burn off some energy. This breed can have some genetic diseases such as:
- Patellar deviation;
- Cryptorchidism;
- Hydrocephalus.
Patellar deviation is a disease where the animal may limp and feel local pain, as the patella leaves the anatomical place, which may lead to injuries from temptation and other complications.
Cryptorchidism is the disease present in males where one or both testicles are not observed in the scrotum. The puppies are born with the testicles in the cavity and until 8 months these testicles tend to be in the scrotum.
After 8 months of the absence of one or more testicles the animal is considered cryptorchid. In these cases, castration of the animal is indicated, since the testicle in the cavity has a greater predisposition to become a tumor that can worsen the health of the animal.
Hydrocephalus, on the other hand, has no well-described causes. It is the disease that happens in the intra uterine life where there is a large accumulation of liquids in the puppy’s skull. Thus, the bitch may have difficulties when giving birth to the animal in a natural way, being a necessary cesarean section. Puppies often die due to neuronal complications generated by hydrocephalus.
Dogs with these genetic disorders are discouraged from breeding. And there must be veterinary monitoring for better resolution of the cases.
These animals do not have so many reproductive problems, but gestational follow-up with a veterinarian is advised due to the high incidence of hydrocephalus, which can lead to dystocia, resulting in the mother and the offspring’s death.
