A reputable dog breeder tries, if possible, to avoid breed-typical diseases in the Chihuahua. However, a certain predisposition to certain ailments and complaints can still remain.
Heart problems and other chihuahua diseases
Many small dogs, such as the Chihuahua, can develop so-called mitral regurgitation from the age of eight. This is a heart disease in which the mitral valve no longer closes properly. Blood then flows from the left ventricle into the left atrium and the heart muscle has to pump harder. However, with regular checkups and timely therapy, the chihuahua can live well with the disease.
Chihuahuas, like Yorkshire Terriers and other small breeds, also run the risk of suffering from a patellar luxation. This describes a kind of connective tissue weakness through which the kneecap can pop out and move in the joint. Depending on the degree of severity, this only happens with pressure or with simple movements. In addition, the mini dogs can develop progressive retinal atrophy, an eye disease that leads to blindness. Tiny chihuahuas and chihuahua puppies, in particular, can also be hypoglycified more often.
Warning signs for diseases? Off to the vet!
A Chihuahua tends to sneeze backwards due to inheritance. This is noticeable in the fact that the mini dog suddenly breathes and wheezes. This often happens when there is excitement and initially has a scary effect on the dog owner. However, you do not need to go to the veterinarian immediately, because if you calm down your Chihuahua and massage the neck very gently towards the body, the attack subsides.

However, if your dog appears to be very restless, sleep a lot, feel weakened and apathetic or otherwise behave abnormally, you should have this clarified by the veterinarian. This also applies if the Chihuahua has digestive or appetite disorders, is paralyzed or limps or trembles heavily.
