Apple Head vs. Deer Head Chihuahuas

Chihuahuas are Australia’s tiniest dog breed, but what many new owners don’t realise is that not all Chihuahuas are shaped the same. There are two distinct head types: Apple Head and Deer Head. Each brings its own appearance, history, and potential health quirks.

If you’re considering adding one of these pocket-sized companions to your household, understanding the difference between these two types is more than just trivia. It can affect everything from your dog’s vet visits to their show eligibility. So, what sets an Apple Head apart from a Deer Head?

The Apple Head Chihuahua: A Classic Look

Apple Head Chihuahuas are the breed standard as recognised by global bodies like the American Kennel Club (AKC). Their skulls are rounded, almost dome-like, with a pronounced 90-degree angle where the forehead meets the snout, a feature breeders refer to as the “stop.”

Physical Traits:

• Rounded skull
• Shorter muzzle
• More prominent eyes
• Shorter jaw and wider face
• Compact body and shorter legs

These features contribute to the “puppy-like” look that many buyers find irresistible. Apple Heads are commonly seen in dog shows and are more likely to meet the breed standard if you’re looking for a show-quality pup.

Health Considerations:

One anatomical feature worth noting is the molera, a soft spot on the top of the skull that resembles a fontanelle in human babies. Most Apple Heads are born with this opening, which may or may not close as the dog matures. While not necessarily dangerous, the molera does make their head more vulnerable to trauma. Jumping off couches or rough play with larger dogs can pose a risk.

Apple Heads are also more prone to:

• Brachycephalic syndrome due to their shorter snout
• Dental crowding
• Hydrocephalus (an abnormal buildup of fluid in the brain)

That said, responsible breeding can reduce these risks significantly.

The Deer Head Chihuahua: A Leaner, Longer Look

Deer Head Chihuahuas, while not typically eligible for conformation shows, are just as popular among pet owners for their distinctive look and potentially fewer health problems.

Physical Traits:

• Longer, sloped snout
• Flatter skull with less defined stop
• Taller, more elongated body
• Longer legs
• More proportional jaw

The “deer” label comes from their resemblance to a young fawn—elegant, narrow-faced, and slightly leggier.

Health Considerations:

Because of their longer muzzles, Deer Heads are less likely to suffer from respiratory problems linked to brachycephaly. They also tend to have better dental alignment and fewer issues with overcrowded teeth.

However, they can still experience:

• Luxating patellas (kneecap dislocation)
• Collapsing trachea
• Hypoglycaemia in puppies
• Eye injuries due to prominent eyes (common in both head types)

Are These “Types” or “Breeds”?

Technically, Apple Head and Deer Head Chihuahuas are not separate breeds. They’re simply head shape varieties within the Chihuahua breed. While both types can be registered as Chihuahuas, only Apple Heads conform to the show ring expectations. This difference often influences pricing: show-line Apple Heads from pedigree lines may cost more than Deer Heads.

Behaviour: Does Head Shape Affect Temperament?

There’s no concrete scientific evidence linking head shape to personality. However, anecdotal accounts from long-time breeders and owners suggest that Deer Head Chihuahuas may be slightly more active and agile due to their build, while Apple Heads may be more lap-oriented and relaxed.

That said, temperament depends far more on early socialisation, training, and genetics beyond head shape.

Which One Is Right for You?

Ask yourself a few key questions:

• Do I want a show-quality dog? → Go with an Apple Head.
• Do I want a potentially lower-maintenance dog? → Deer Head might be your match.
• Am I worried about the molera or brachycephalic risks? → Lean toward Deer Head.
• Do I prefer a compact or leaner appearance? → Apple Heads are shorter and stockier; Deer Heads are taller and sleeker.

If your main goal is companionship, either type will deliver heaps of loyalty, sass, and cuddles in a tiny package.

Shopping Smart: Why Head Type Shouldn’t Be the Only Factor

Regardless of head shape, always choose a reputable breeder who prioritises health, ethics, and proper socialisation. Steer clear of anyone advertising “teacup Chihuahuas” or promising unusually tiny dogs—these often come with a host of genetic and developmental issues.
