Molera in Chihuahuas: Understanding the Soft Spot

Historically, the Chihuahua, as developed in Mexico and the United States, has exhibited a unique characteristic known as the Chihuahua molera, which is a soft spot on Chihuahuas located on the top of the head. This spot, or fontanel, resembles the soft spot found in human babies. In the past, the presence of a molera was regarded as a sign of purity in the Chihuahua breed standard, and it continues to be mentioned in breed standards globally. It's essential to understand that while many Chihuahua puppies are born without a molera, there are just as many that do have one, and this is nothing to be alarmed about. The illustration shows that the molera in a Chihuahua can vary in shape and size when it is present.

While it would be impossible to cover all the medical documentation on this topic here, the information available clearly indicates that the presence of a molera does not signify any medical issues for the Chihuahua. This little dog thrives in the home, by their owner's side, and deserves plenty of love. Whether with or without a molera, a healthy Chihuahua that receives proper veterinary care can live well into their teens, becoming an irresistible family member. As noted by The Chihuahua Club of America, Inc.

The American Kennel Club specifically mentions the molera in the Chihuahua breed standard. This soft spot on the head is very similar to what is found on a human baby’s head. Newcomers to the breed should understand that this feature is common in most apple head Chihuahua puppies. Although the molera often closes as the puppy ages, there are instances when it may not close completely. Historically, before the establishment of breed registries, the molera served as a strong indicator that the puppy was indeed a pure breed Chihuahua. Before bringing your new puppy home for that initial vet check-up, it's important to educate yourself about this breed characteristic. Many veterinarians familiar with the Chihuahua breed will note the presence of a molera in their reports, but some may not have specific knowledge about the breed and could cause unnecessary alarm for pet owners.

We primarily breed for the apple head, which means nearly all of our puppies will have a molera when they go to their new homes. Through the years, we've observed that some veterinarians may not be specialized in the Chihuahua breed, resulting in unwarranted concerns about the presence of a molera in their new puppies. Please do not be alarmed; it’s important to educate yourself, and if needed, bring a copy of The Chihuahua Club of America’s statement regarding the molera to your vet appointment. Engaging with other Chihuahua owners in your area may also help you find a veterinarian who specializes in toy breeds, especially Chihuahuas.

A knowledgeable vet who understands the Chihuahua breed is invaluable to a Chihuahua owner. However, it's crucial to recognize that not all veterinarians will be familiar with the specific details of the breed, which can lead to unnecessary worry for pet owners. Finding a veterinarian who is well-versed in the Chihuahua breed may take some time and effort.
