The Chihuahua is considered to be a moderate shedding dog. A puppy will go through a stage in which puppy fur will shed off and give way to his adult coat. This process begins at the age of 5 to 6 months.

For adults, the details of the shedding process are vastly different, depending on the coat (long or short) and gender. If there is substantial fur loss without apparent reason, this may point to a medical issue.

Males: Once reaching 18 months of age, a male's coat will stay relatively the same for its life.

Females: Hormonal fluctuations and the change of seasons often affect a female's coat. Females will also shed after delivering a litter and her coat will re-grow back in about 6 months.She will also shed when she is in season. Stress can affect the degree of shedding as well.

Both Genders: Aesthetics will affect the coat. See: Hair Loss and Shedding

Dental Care 

This breed is prone to dental issues that include: tooth infection, gum infection. This can lead to: Secondary infection and loss of teeth.

Canines do not develop cavities in the way that humans do; however both plague and tarter do build up over time. Chewing on hard treats does help to loosen plague, but will not clean the teeth enough to prevent issues from developing.

As bacteria builds up, teeth weaken and bone is gradually destroyed, resulting in either loss or the need for extraction. Tooth loss for an older Chihuahua can cause disturbances in abilities to eat and cause quite a bit of discomfort.

Following a schedule of dental care should be part of routine care provided for a Chihuahua and is an important part of having a healthy dog. Training a Chihuahua to sit still for this grooming element is best done when the Chi is still a puppy. Becoming acclimated to having his mouth manipulated will lead to good habits as he grows older.

While the Chihuahua can be a vocal dog, training can be very successful, especially when started early.

Excessive barking is one of the top concerns for Chihuahua owners. This vocal behavior can be traced to 3 different triggers:

1. Separation Anxiety - It is common for companion dogs such as the Chihuahua to form very close attachments to his human family members, and to feel stress when home alone.

2. Boredom - While some Chi's can have an independent streak, most thrive on human companionship and interaction. Left to entertain himself, a Chihuahua may bark excessively.

3. Improper reaction to stimuli. Some Chihuahuas will need Socialization Training to learn how to react to visitors, strangers and to other dogs. Read more: Barking

Interesting Facts
  • Chihuahua’s brains are the largest of any breed, when compared to the size of their bodies. 
  • In 1997, a Chi named Gidget starred as the Taco Bell dog in global television commercials, thus bringing attention of the breed across the world.  
  • Not all Chihuahuas shake, but many do and it is considered to be a common trait, though not due to the widespread myth that this is due to having a high metabolic rate. Actual reasons for trembling include excitability, nervousness or feeling chilled. 
  • This breed is loved in Hollywood. Some celebrity Chihuahua owners are: Jamie Lee Curtis, George Lopez, Hillary Duff and the late, great Marilyn Monroe
  • Many Chihuahuas have a molera. This is a soft spot on the skull where the bones have not fused together (similar to human babies). Back in 1933, the breed standard required a molera. Now, the Chihuahua Club of America (the parent club that writes the standard for the AKC) tells us that it may or may not be present (no favor is given to either in the show ring).
  • A Chihuahua is an adult at the age of 1 year old. While there is no official age that the Chi becomes a senior, most are declared to be seniors by the age of 10. With a rather long lifespan, this breed can live 14 to 18 years.
The Interesting Origin of the Chihuahua 

The Chihuahua is named for the Mexican state of ‘Chihuahua’ that borders Texas, Arizona and New Mexico in the USA. Though it has long been theorized that the Chihuahua’s ancestors were from Chihuahua (the Mexican state), this has been confirmed by DNA analysis. 

It was long theorized that the Chihuahua's ancestor was the Mexican Techichi dog and now we know this to be fact. 

Any online sources or books that debate a Mexican origin for the Chihuahua are offering out-of-date information. In 2013, the KTH Royal Institute of Technology in Stockholm, Sweden released their findings regarding the ancestry of certain dog breeds. They compared mitochondrial DNA from Asian and European dogs, ancient archaeological samples from the Americas and certain American dog breeds. Among the breeds that that they tested was the Chihuahua, since its origins have long been debated. They proved that the Chihuahua does share a DNA type unique to the Mexican pre-Columbian samples, thus cementing the breed’s origins to be connected to the Techichi, a small desert canine that dates back to Mayan times. 

Crossbreeding the Techichi may have been done by the Toltec civilization with a dog that populated the mountains of Chihuahua, called the Perro Chihuahueno. Further development occurred when Spanish conquerors reached the New World, though it is debated which breeds were used; most likely it was a terrier-type dog.

The Chihuahua was officially recognized by the AKC (American Kennel Club) in 1904, with a Chihuahua named Midget being the very first to be registered. At that time, the club was only 20 years old (having been founded in 1882). And in 1904 only 52 breeds had been recognized thus far. 

The Chihuahua’s popularity took a while to form. This is because in the early 1900’s most people that owned dogs owned working dogs or guard dogs, not household pets. People living on farms used dogs to pull carts and herd livestock. Others owned dogs to chase away wild animals or possible intruders. 

Things began to change in the 1960’s when ‘dog ownership’ moved more into ‘pet ownership’. In 1964 the Chihuahua soared to popularity, becoming the 12th most registered breed. In this year, there were 161 recognized breeds. Since that time, the Chihuahua has held its place in the top 30. Ranking in 2013 was #22, in 2014 #24 and in 2015 #28. Though the ranking has dropped a bit, we must remember that more breeds are added as the years go by. At the time of this writing, there are 189 recognized breeds. 

For 48 years since its inception into the AKC, both long and shorthaired Chihuahuas were categorized the same. In 1952, The Chihuahua Club of America, which writes the breed standard for the Chihuahua, voted to split the Chihuahua into two varieties. The same standard is used; however, the two varieties are long coat and smooth coat (short haired).
