Molera in Dogs: Symptoms and Diagnosis

What is It?

Like humans, some dogs’ skull bones are not completely fused in place at birth. Molera is the “soft spot” on a dog’s head.

What Causes It?

A molera is a small opening either diamond or circular shaped at the upper center of the dorsal skull. A molera may or may not close. It is most common in chihuahua’s and was once said to mark the purity of the breed.

It is not technically a medical abnormality. The presence of a molera does increase the dog’s risk of trauma to the brain.

How is It Diagnosed?

A physical exam is typically enough to diagnose the molera. Some vets will suggest an ultrasound to check for the presence of hydrocephaly.

What Are The Treatments?

The best course of action is to practice caution in your pup’s daily activity. Do not allow jumping from heights or any rough play especially with small children that may not understand the limits of the dog’s skull.
