Chihuahua
Trait scores are tendency indicators from 0-100. Example: 42% alone tolerance roughly maps to around 4 hours alone.
Chihuahuas are tiny dogs with huge personalities who often don't realize they weigh only a few pounds. These ancient Mexican companions are loyal, sometimes possessive dogs who bond intensely with one or two people, and their small size masks a tendency toward fearful aggression when not properly socialized, making them surprisingly challenging to raise.

Watch Out For
A Day in the Life
A purposeful walk and short training game helps them settle for the day.
Most do best with another activity block before winding down near their people.
Longer outings and enrichment games noticeably improve behavior and sleep quality.
People often underestimate how quickly behavior slips when routines are inconsistent.
Exercise & Activity
Plan on around 60 minutes of daily activity split between walks and mental games. Consistency matters more than occasional long outings.

Mental Enrichment Ideas
Health
Long-term outcomes improve with weight control, regular preventive care, and condition-specific monitoring for known breed risks.
Known Health Concerns
Abnormal hip joint development can lead to pain and arthritis over time.
Environmental allergies can cause chronic itching and recurrent skin or ear issues.
Plaque and periodontal disease are common without consistent home dental care.
Size, exercise demand, and care complexity determine boarding availability and price.
Behavior Reality Check
These are potential challenges that many Chihuahua owners encounter. Being aware of them helps you prepare and manage them effectively.
Potential Reactivity
Mitigation Strategy:
Professional training recommended, controlled socialization, avoid trigger-rich environments initially.
Remember: These are breed tendencies, not guarantees. Individual dogs vary based on genetics, training, and environment. Early socialization and consistent training make a huge difference.

Shedding varies by coat type; double-coated breeds and many mixes shed heavily during seasonal coat changes.

Breed History
Origin
The Chihuahua originated in United Kingdom.
Original Purpose
Chihuahua lines were developed for companion. That working role still shows up today in temperament, stamina, and day-to-day needs.
Breed Group: Toy. Toy breeds were developed mainly for companionship in small bodies. They are often people-focused and adaptable indoors.
In modern homes, this history matters because it predicts what helps the dog thrive: enough movement, clear structure, and outlets that match their original instincts.
Fun Facts
Chihuahuas aren't naturally tiny—they were miniaturized from a larger Mexican breed called the Techichi, and this happened so recently (1800s) that some still have genetic 'throwback' giants.
A Chihuahua's skull is proportionally the largest of any dog breed relative to body size, making their brains enormous compared to their body weight.
The breed has a 'molera'—a soft spot on the skull like a human baby—that never fully closes in many individuals, making them surprisingly fragile.
Chihuahuas are one of the most abandoned breeds in shelters because owners massively underestimate how aggressive and territorial they can be (they have the highest bite-per-capita rate of any breed).
The breed's history is murky, but they're theorized to descend from pre-Columbian Mexican dogs that were considered sacred and used in religious ceremonies.
