10 Essential Facts About Chihuahuas Before You Buy One

The Chihuahua is the world’s smallest dog breed, often surprising first-time observers with its tiny stature. This petite, delicate size combined with undeniable charm makes Chihuahuas highly sought-after pets in the UK. Many celebrities owning this breed have raised its profile further, contributing to the surge in popularity.

However, the surge in demand sometimes means prospective owners don’t do enough thorough research before purchase. This can lead to unpreparedness for the specific care and lifestyle a Chihuahua requires.

Before buying any dog, careful research and reflection are essential. This article provides ten crucial things you need to know about Chihuahuas, supporting you to make a well-informed, responsible decision.

1. Popularity and Availability in the UK

The Chihuahua is the second most popular dog breed in the UK by advert listings, making it easy to find puppies, but this popularity also increases risks of impulse purchases. Meeting Chihuahua owners locally can give valuable insights into living with the breed.

2. Their Size and Delicacy

Chihuahuas average 15-25cm in height and up to 2.7kg in weight. Their small size means they have delicate bones and require gentle handling to avoid injuries. Their metabolism is rapid, mandating exact food portioning and routine meals to maintain healthy weight.

3. Balancing Safety and Natural Lifestyle

Owners must find a balance between allowing natural play and keeping their Chihuahua safe due to their vulnerability, especially around larger dogs. Overprotecting can negatively impact their socialisation and wellbeing, but vigilance is necessary to prevent accidents and harm.

4. Distinct Head Shapes

There are two primary head shapes among Chihuahuas: the widely recognised domed “apple head” and the less common “deer head” with a longer muzzle. The deer head variant tends to be rarer and may require more searching when buying.

5. The Fontanelle (Molera) Soft Spot

Many Chihuahuas are born with a molera or fontanelle—a soft spot on the skull. In some dogs, this closes with age, but if it remains open, owners must protect the skull carefully to avoid injury.

6. Beware of “Teacup” Chihuahuas

Some breeders produce extremely small "teacup" Chihuahuas, often from runts or unhealthy lines, which may suffer from poor health and fragile constitution. Avoid these variants and seek reputable breeders focused on healthy dogs; more information is here.

7. Commonly Surrendered Pedigree Breed

Despite their popularity, Chihuahuas are one of the pedigree breeds most often surrendered to UK shelters due to owners underestimating care demands and training needs. Responsible ownership and early training reduce these issues significantly.

8. Proper Training and Treatment

Chihuahuas are dogs, not toys; they must be trained consistently with clear boundaries, socialised well with other dogs and people, and given routine exercise. Impulse buyers often carry them excessively and fail to socialise or train, leading to behavioural problems such as aggression or dominance.

9. Health Considerations

While generally hardy, Chihuahuas face specific health challenges including dental disease, luxating patella (slipping kneecap), hypoglycaemia (low blood sugar), and heart conditions. Routine vet checks and awareness of hereditary problems support their health^[source].

10. Theft Risks and Safety Measures

Due to their small size and high demand, Chihuahuas are targets for theft. Always ensure your dog is microchipped, wears an ID tag, and avoid leaving them unattended outdoors or in cars. Be cautious when strangers offer to look after your dog, and secure your home to protect your pet.

How to Keep Your Chihuahua Safe and Happy

Creating a secure home environment free from hazards, alongside supervised outdoor activities, promotes safety. Use a secure harness on walks, avoid overly hot surfaces, and provide socialisation in controlled settings. Preparing a first aid kit and knowing your vet’s emergency contacts is advisable.

For exercise, short daily walks and playtime suffice. Groom appropriately for coat type and maintain dental hygiene diligently. Training should be consistent, patient, and involve the whole family to build a well-mannered, confident dog.

Where to Find a Reputable Chihuahua Puppy

Choosing a reputable Chihuahua breeder is essential for health and temperament. Look for breeders who perform health testing, provide socialisation before sale, and adhere to ethical breeding standards. Alternatively, consider adopting from UK rescues that specialise in small breeds, helping to reduce unwanted dogs.

Remember, buying a dog should never be impulsive. Taking time to educate yourself on the breed’s characteristics, care needs, and potential challenges will result in a happier life for both you and your Chihuahua.
