Chihuahua Head Shapes: Apple Head vs Deer Head
The Chihuahua is the world’s smallest dog breed, hugely popular due to their tiny size and lively personalities. They are instantly recognisable by many dog lovers, especially because of their distinctive head shapes.
There are two main recognized Chihuahua head shapes: the "apple head" and the "deer head." These terms define the structure of the skull and facial profile, influencing both the dog's appearance and health.
1. Understanding Chihuahua Head Shapes
Apple Head Chihuahua
Apple head Chihuahuas have a broad, rounded skull that resembles an apple, often with a sharply defined “stop” between the forehead and short muzzle. Their domed skulls are prominent, and their large, round eyes are often wide and expressive, sometimes appearing prominent. This head type is typically accompanied by a compact body, shorter legs, and a delicate frame. They generally weigh between 2 to 6 pounds.
Deer Head Chihuahua
Deer head Chihuahuas feature a longer, narrower skull with a gentle sloping profile, resembling a young deer. The angle between the forehead and muzzle is more gradual, approximately 45 degrees. Their muzzles are longer, eyes less protruding, and ears proportionally larger, giving a more balanced and delicate appearance. They tend to be taller and heavier than apple heads, sometimes weighing up to 12 pounds with longer legs and neck.
2. Breed Standard and Show Eligibility
Within the UK, the Kennel Club's Chihuahua breed standard prefers the apple head shape, described as a "well rounded with an apple dome" skull. The show standard demands that while eyes should be large, they must not protrude excessively. Consequently, only apple head Chihuahuas conform to the official breed standard and are eligible for conformation shows.
Although deer head Chihuahuas are not recognised for show competitions, they remain true Chihuahuas with the breed’s typical traits and personality. Responsible breeders prioritise health, often valuing deer head types for their more natural and less exaggerated conformation.
3. Health Considerations of Head Shapes
Apple head Chihuahuas often have a distinctive soft spot on top of the skull known as a molera. This is similar to a human baby’s fontanelle and sometimes remains open for life. While a molera itself does not cause health issues, it makes the skull more susceptible to injury and requires careful protection.
Apple heads with highly exaggerated domes and large eyes can be prone to specific health problems such as tracheal collapse, dental issues, and overheating due to their flatter muzzles. This excessively domed skull shape can sometimes affect breathing and eye health.
Conversely, deer head Chihuahuas have a more proportionate skull and muzzle, reducing risks associated with breathing difficulties and tracheal collapse. Their slightly larger muzzles and less prominent eyes generally mean they are less susceptible to common conformational health problems seen in apple heads.
4. Making the Right Choice: Health vs Show Potential
If you’re considering finding a Chihuahua puppy, it’s important to weigh the pros and cons. While apple head Chihuahuas are show ring favourites, priority should be given to the dog’s health and wellbeing rather than appearance alone.
Responsible breeders who breed within the breed standard but focus on healthy proportions will usually produce apple head Chihuahuas less prone to exaggerated health issues. Meanwhile, deer head Chihuahuas are often overlooked in shows but may enjoy a healthier life with fewer conformational problems.
Understanding these differences can help you make a more informed, compassionate choice when adopting or buying a Chihuahua pup, focusing on responsible ownership and animal welfare.
5. Key Questions When Buying a Chihuahua Puppy
- Is the breeder reputable and prioritising health over exaggerated features?
- Does the puppy’s head shape align with what you value — show potential or health considerations?
- Is the puppy free from signs of health problems commonly associated with the head shape?
- Has the puppy undergone initial veterinary checks and vaccinations?
Asking these questions respectfully to breeders helps ensure you bring home a happy, healthy Chihuahua suited to your lifestyle.
Conclusion
Chihuahua apple head and deer head shapes each have unique traits affecting appearance, show eligibility, and health. While the apple head is preferred for conformation shows, the deer head is often healthier and less prone to specific conditions related to skull shape. Both forms share the lively, loving personality that endears Chihuahuas to families and individuals alike.
When choosing a Chihuahua, focusing on responsible breeders that emphasise health and temperament over extreme looks supports the welfare of these little dogs, ensuring many joyful years together.
