Chihuahuas are fantastically popular dogs that are available in several different flavors, including nine different colors, six different patterns and both long- and short-haired varieties. But there is one more way in which Chihuahuas vary – the shape of their heads!
Many owners are unaware of this fact, so be sure to keep reading. We’ll explain how to tell the difference between the two, as well as provide guidance so you can select the best one for you.
Apple Head vs Deer Head Chihuahua Skull Shape
Chihuahuas display one of two different skull shapes: apple-like or deer-like. At the risk of being painfully obvious, apple head Chihuahuas have heads shaped like apples, while deer head Chihuahuas have heads shaped like — wait for it — the heads of deer.
It’s usually pretty easy to distinguish the two, but if you are having trouble, look at the place where your Chihuahua’s muzzle meets his face from the side. Apple head versions will have a roughly 90-degree angle at this point, while the same part of a deer head Chihuahua will be about 45 degrees.
Simply put, the apple head Chihuahuas feature a face that is essentially vertical, the faces of deer head Chihuahuas are sloped. Additionally, the forehead of apple-shaped chihuahuas is much more prominent than those of deer-headed individuals.
In the photo of the apple headed Chihuahua below, note the:
- rounded head
- short snout
- prominent forehead
- bulging eyes
The large eyes and small, rounded head makes the apple headed Chihuahua appear physically reminiscent to a human baby – which is one reason why we humans find these Chihuahuas so darn cute!
In the photo of the deer headed Chihuahua below, note the:
- more elongated, oval head
- longer snout
- less pronounced forehead
There are a number of other differences between the two varieties, but these are the most noteworthy. We’ll discuss the other differences a little later on.
Apple-Headed Chihuahuas Are the Breed Standard
Technically, to conform to the AKC breed standard, Chihuahuas must have “apple-shaped heads.” So, if you are interested in showing your dog, it is important to look for an apple head variety. However, there is certainly nothing wrong with deer head Chihuahuas, and a few have even become famous.
Additionally, as long as both of your Chihuahua’s parents were AKC-registered, you can register your Chihuahua, no matter what shape his head is. There is always the possibility that the AKC (and other registration clubs) will start recognizing two separate varieties, but only time will tell. This is a contentious subject among those who work with the breed.
Which Came First? The Apple or the Deer?
Nobody knows exactly why or how Chihuahuas began producing differently shaped heads. In general, the breed’s history is somewhat complex and unclear.
Some sources report that remains of Chihuahuas that lived thousands of years ago, representing both varieties have been collected. This complicates the situation and makes it likely we’ll never know exactly which skull shape came first.
Interestingly, apple head Chihuahuas occasionally appear in litters produced by two deer heads, and vice versa. However, this doesn’t appear to occur in any sort of predictable pattern – you never know when you’ll get a surprise!
What Else Is Different About Deer Head and Apple Head Chihuahuas?
Aside from head shape, the two different kinds of Chihuahua exhibit several other differences. Some of the most noteworthy differences include:
Most apple head varieties have a soft spot on their skull at birth (termed a molera), this is less common with deer head varieties.
Deer head Chihuahuas usually have longer heads, necks and legs than their apple head counterparts do.
Deer head versions are generally longer and leaner than apple head Chihuahuas.
The eyes of apple head Chihuahuas typically appear more pronounced, given the shape of their heads.
Conversely, the ears of deer-headed Chihuahuas appear more prominent and are set higher on the head than those of apple-headed Chihuahuas.
While still basically similar in size, deer-head Chihuahuas are often slightly larger than the other variety.
In addition to differently shaped skulls, the different types of Chihuahuas also have different jaw lengths: Deer-headed versions have much longer jaws than apple-headed versions do.
Some who are familiar with the breed consider deer head Chihuahuas to be the more relaxed of the two.
Most Chihuahua authorities believe that the deer-headed variety is less susceptible to health problems than their apple-headed counterparts.
Are There Any Benefits of Buying One or the Other?
For the most part, you should feel free to select whichever type of Chihuahua you like best. If you think that apple head versions are too cute for words, then go ahead and add one to your family; but if you’d prefer a deer-headed doll, go with the that version.
However, there are a few important considerations to keep in mind when making your choice. For example, if you dream of dog shows and blue ribbons, you’ll be forced to select an apple head Chihuahua. Conversely, if you don’t have any aspirations for the show ring, deer head Chihuahuas may be the better choice (assuming you prefer their look or other traits).
Most Chihuahuas generally favor one type or the other; however, a small percentage of these spunky little pooches feature a mixture of the traits common to both varieties. So far, nobody is exactly sure why this happens, and you never know when such an unusual individual will pop up in a litter.
These combination Chihuahuas may exhibit some traits commonly associated with one of the varieties, as well as traits that are associated with the other variety. It’s likely that you have one of these combination varieties if you have a difficult time identifying your pet as one or the other.
What say you, good readers? Do you prefer one style of Chihuahua to the other? What kinds of differences have you noticed between the two varieties?
We’d also love to take the pulse of the Chihuahua community and find out if there is much of an appetite for a change in the AKC’s standards. Do you think they should continue to recognize only one type of Chihuahua, or should they split the breed into apple- and deer-headed varieties?
