Where Is the Soft Spot on a Chihuahua? Understanding Fontanels

The soft spot on a Chihuahua’s head is called a fontanelle and usually closes up by 6 months of age. During this time, the puppy’s skull bones are still developing and the fontanelle allows for flexibility and room for growth. It’s important to be gentle around this area and avoid putting pressure on it to prevent injury.

Fontanelle – What You Need to Know

Chihuahuas are a small breed of dog that are known for their affectionate and loyal personalities, and have a soft spot on the top of their heads called a fontanelle. Chihuahuas come in two varieties: the smooth coat and the long coat, and can be found in various colors including black, white, cream, fawn, or brown. The average Chihuahua stands between 5 to 8 inches tall at the shoulder. They generally weigh no more than six pounds when fully grown.

According to breeding standards set forth by The American Kennel Club (AKC), all Chihuahuas should possess certain characteristics such as an alert expression and saucy disposition. Chihuahuas tend to be protective of their owners and may bark if they sense danger or feel threatened. They do not require much exercise but love being around people and other animals; therefore they make great companions for both children and adults alike. Although they may appear fragile due to their size, Chihuahuas are actually quite resilient dogs with plenty of energy!

The soft spot at the top of a Chihuahua’s head is called a fontanelle; this usually closes up by 6 months of age but some may take longer depending on individual growth rates. All puppies have fontanelles but it is more pronounced among toy breeds like the Chihuahua because these breeds typically have thinner skulls than larger dogs. It is important to note that these spots can still be sensitive even after closing up so it’s best not to touch them too much or cause any discomfort for your pup!

It’s important to remember that while all dogs need love and care no matter what breed they are, there are some unique considerations when you own a Chihuahua due to its small size. Make sure you provide your pup with proper nutrition, enough exercise time every day, regular vet visits for check-ups, as well as plenty of positive reinforcement training in order for your pup to grow into a happy adult dog!

What is the Fontanelle?

You may not know it, but a special surprise is tucked away beneath the fur on your pup’s head – the Fontanelle! This soft spot is also known as a molera, and is found on all Chihuahuas. It is usually located slightly above the center of their forehead.

The fontanelle serves an important purpose for young pups; it helps to protect them during birth by providing extra space in case of large-headed puppies or difficult deliveries. The fontanelle also allows room for brain growth in puppies who are still developing their cognitive skills.

When socializing Chihuahuas, it’s important to be aware of this soft spot! According to breed standards, some owners even opt to cover up the area with a bandana or bow for protection while out and about.

However, as puppies grow older, the fontanelle will eventually close up and become less noticeable over time. By 6 months of age, most Chihuahua’s fontanelles will have closed completely and no longer be visible or present any risk of injury due to its closure.

Chihuahuas are fragile creatures that require special care when they are young and growing into adulthood. Being aware of their delicate soft spot can help ensure that your pup stays safe while learning how to navigate new surroundings and experiences with proper socialization techniques.

Additionally, keeping an eye on this area can help you detect any issues such as bumps or raised spots which could indicate potential health problems like hydrocephalus (the buildup of fluid around the brain).

It may seem like there’s nothing too special about this small patch of fur at first glance – but knowing more about where it comes from can give you peace of mind regarding your pup’s health and wellbeing! Knowing what to look for in regards to the fontanelle can be incredibly helpful when it comes time for regular check-ups with your veterinarian too!

Where is the Soft Spot Located?

Tucked away just above the center of your pup’s forehead is a special surprise – the fontanelle! This soft spot, known as the bregma, is located between a Chihuahua’s ears and acts as an access point to their skull. It closes up by 6 months of age, but while it’s open it serves various purposes.

  • Fostering Trust: A baby Chihuahua relies on its mother for protection. The fontanelle can be used as an access point for the mother to carry her pup safely and securely.
  • Brain Development: As puppies grow, they require oxygen to reach their brain in order to develop properly. The fontanelle provides a wide opening that helps facilitate this process.
  • Breed Selection: Since Chihuahuas are so small in size, breeders often use the fontanelle as an indicator when selecting which puppies should become part of their breeding program. The larger or more prominent the fontanelle appears, the better fit it may be for breeding purposes.

As you can see, having a soft spot on a Chihuahua’s head is not only important from a safety standpoint but also plays an integral role in their development and future success as members of our canine family!

Developmental Stages of the Fontanelle

The fontanelle, often referred to as the pup’s ‘soft spot’, develops in stages and usually closes by six months of age. Chihuahuas are a small breed, with their head circumference being much smaller than larger breeds. As a result, the fontanelle tends to close more quickly than other breeds. The closure of the fontanelle is an important breed characteristic, and this process should be monitored closely in order to ensure proper health for your pet.

At birth, the soft spot on a Chihuahua’s head is large and open. Over time, it will gradually decrease in size until it eventually closes completely at around six months old. During this period of development, there are several signs that indicate the closure of the fontanelle such as reduced flexibility or bulging on both sides of the skull when pressed down upon gently.

As your pup grows older and reaches six months of age, it is important to watch for signs that may indicate that the fontanelle has started closing prematurely or too slowly – these can include changes in fur texture or overall appearance around the area where the fontanelle was located previously. If you notice any irregularities during this stage, it’s recommended that you consult a veterinarian as soon as possible so they can assess whether further medical intervention is necessary.

It’s essential for all pet owners to understand how their chihuahua’s breed characteristics affect its development and overall health throughout its life-cycle. Monitoring your pup’s progress with respect to its fontanelle closure ensures they receive proper care and attention during their early stages of growth – ensuring a happy and healthy adulthood!

Potential Health Concerns

Though small, Chihuahuas can be susceptible to a variety of health problems regarding their fontanelle. It’s important for pet owners to be aware of the signs of distress or common diseases that may affect their pet’s fontanelle.

The most common sign is when your Chihuahua’s fontanelle appears inflamed or swollen. This could be an indication that there are underlying issues going on, such as infection or injury. If you notice any signs of distress in your pet’s fontanelle, it’s important to seek veterinary attention right away.

Another potential health concern related to the fontanelle in Chihuahuas is hydrocephalus. This condition occurs when cerebrospinal fluid accumulates within the skull and puts pressure on the brain, resulting in neurological symptoms such as unsteady gait and seizures. Other symptoms may include an enlarged head size, a bulging fontanelle, and mild lethargy.

If hydrocephalus goes untreated, it can lead to permanent brain damage or death due to increased intracranial pressure and decreased cerebral blood flow.

In some cases, tumors may also develop around the area where the soft spot used to be located on a Chihuahua’s head. These tumors can range from benign growths such as lipomas (fatty deposits) to more serious malignant tumors that might require surgical removal if caught early enough.

Pet owners should keep an eye out for any unusual lumps or bumps appearing near the area where the soft spot once was on their pup’s head and contact their veterinarian immediately if anything suspicious appears.

It’s also important for pet owners to watch for any changes in behavior which might indicate a problem with their Chihuahua’s fontanelle – this could include sudden lethargy, loss of appetite, difficulty walking etc. All these signs should prompt consultation with a veterinarian so they can diagnose what’s wrong with your pup quickly and provide them with appropriate care sooner rather than later!

Care and Monitoring of the Fontanelle

Caring for a Chihuahua’s fontanelle requires close attention and consistent monitoring to ensure their health and safety.

This means checking the fontanelle regularly for any signs of redness or swelling, as these can be indicators of infection or injury.

Additionally, it’s important to monitor the size of the fontanelle. If it becomes larger than normal, this may indicate an underlying medical condition such as hydrocephalus.

Furthermore, a Chihuahua’s diet should also be closely monitored to provide nutrients necessary for proper growth and development. Foods high in calcium are particularly important, as they can help with bone growth and strengthen the bones that form around the fontanelle.

Finally, regular visits to the vet are essential to detect any changes in your pet’s health early on. Vets will be able to identify any potential issues before they become serious problems and recommend appropriate treatment options for your pet if necessary.

By following these steps, you can help keep your Chihuahua healthy throughout its life by taking care of its fontanelle properly.


You’re now equipped with the knowledge of what a fontanelle is and where to find it on your Chihuahua. It’s important to keep an eye on this soft spot, as it closes up by 6 months of age.

On average, around 85% of all Chihuahuas close their fontanelles before reaching 1 year old. Although many pet owners are unaware of the importance of this soft spot, you can be sure that with proper care and monitoring, your pet will remain healthy for years to come.
