Chihuahua Puppy Molera – Soft spot

Chihuahua puppy molearDid you know that chihuahua puppies are born with a soft spot (molera)? Just like your baby your chihuahua puppies can have a soft spot as well. Most of them close up like they should over time. Most of the spots close up between four weeks and four months. But some chihuahuas have them all their life.

What is Molera

We know it as a soft spot. A molera is an opening in the top of the puppy’s skull that has not fused together. It can be at the top-center of the skull, several inches above the nose. The molera is typically either circular or diamond shape. It is about the size of a dime.

If depends on the breed of the dog and the shape of the dog’s head the shape and size of the spot. Some have smooth edges, others have rough or jagged edges. As the puppy grows, cartilage pulls the skeletal plates together, closing the molera and calcifying the skull.

About 80% to 90% of all Chihuahuas are born with this. It was once considered a mark of purity in the breed. Apple-head chihuahuas, are more likely to develop and retain a molera than their deer-head, because of their smaller heads. The same for the teacup chihuahua, because they are the smaller guys in the breed they have smaller heads.

In order to protect your puppy; you should still take precautions to protect the head from injury. They could sustain brain injury due to trauma to the head until the skull completely closes up. It’s completely normal anatomical feature that usually closes over time. Even if doesn’t close, there’s no evidence linking the molera to any adverse health condition.

Here are few tips to help keep your puppy from getting an injury:

  • Let your veterinarian know about the soft spot
  • Supervise your puppy during playtime
  • Avoid allowing your puppy to play with bigger dogs; a bigger dog could easily bite the soft spot
  • Try not allow your puppy to jump off furniture, steps, or any objects that could cause him/her to lose his/her balance and hit the head
  • Watch your feet to avoid accidentally kicking your puppy in the head

If your puppy hits his/her head and begins acting unusual such as lethargic, trouble breathing, agitation, seizure; take your puppy to the vet immediately.


Normal Life With Molera

The difficulty with owning a dog with this is the constant concern that the spot will get hit and cause the dog problems. The dog is unaware that there is a problem and will be as rambunctious as any other dog would be. You will have to take precaution on how your dog plays throughout his/her life it the spot does not close up.

Some study at one time suggested that the dog will also have hydrocephalus (water on the brain). While puppies with hydrocephalus will commonly have an open fontanel due to the swelling of the brain, this is does not mean that the puppy will have hydrocephalus or have problems if they are born with molera. This is a different condition that can cause molera.

In Conclusion

Molera is a common thing in small breed dogs. The spot should close up on its own. Although, some dogs have it their entire life. Using precautions with these dogs; they can live a normal life even if the spot does not close up. If you think you puppy has molera; ask your vet for advice to keep the puppy safe.
