Pomeranian vs Chihuahua: Which Is Right for You?

Choosing between a Pomeranian and a Chihuahua is one of the most common dilemmas small dog lovers face — and I get it, because both breeds are bold, loyal, and utterly adorable. The honest answer is that the right choice comes down to your lifestyle, your tolerance for grooming, and the kind of personality you want living in your home. I’ve owned my Pomeranian Sash for years now, and I can tell you from daily experience that these two breeds are far more different than they look at first glance.

What I’ve Learned With Sash

• Pomeranians and Chihuahuas share a big-dog attitude in a tiny body, but differ significantly in grooming needs, temperament, and trainability.
• Your living situation, activity level, and time available for grooming will largely determine which breed suits you better.
• Both breeds have real health vulnerabilities you need to know about before you commit.

A Quick Look at Both Breeds

Before diving into the comparison, it helps to understand what each breed was originally built for. The Pomeranian descends from large Arctic sled dogs — which explains why Sash acts like she could run the Iditarod from the comfort of my sofa. According to the American Kennel Club, Pomeranians were bred down in size over centuries and became a favourite of European royalty. Chihuahuas, on the other hand, are one of the oldest breeds in the Americas, likely descended from the Techichi dog kept by ancient Mesoamerican civilisations.

Both are now classified as toy breeds, both are fiercely loyal to their owners, and both have a reputation for being unaware of their own small size. That’s roughly where the similarities end.

Size and Appearance

On paper, these two are close in size. In reality, they look nothing alike.

Sash is a classic orange Pomeranian with that signature cloud of fur that makes her look twice her actual size. People constantly assume she’s heavier than she is. Chihuahuas, by contrast, look exactly as light as they are — all lean lines and oversized personality.

Temperament: Who’s the Bold One?

Both breeds have Napoleon complex baked into their DNA, but they express it differently.

Pomeranian Personality

Pomeranians are curious, alert, and extremely people-oriented. Sash wants to be involved in everything I do — and I mean everything. She’s confident with strangers but not always immediately friendly. She’ll assess a new person from a safe distance, decide whether they’re worthy, and then charm them completely once she’s satisfied. Poms are also vocal. If something moves outside the window, Sash will tell me about it. At length.

Pomeranians tend to bond closely with one primary person but are generally sociable with the whole household. They do well with children who know how to handle small dogs carefully.

Chihuahua Personality

Chihuahuas take the loyalty concept even further — to the point of being possessive. They often bond almost exclusively with one person and can be openly suspicious or snappy with strangers and other dogs. This isn’t aggression so much as it is intense devotion taken to its logical extreme. Chihuahuas are also more sensitive to cold and more likely to shiver in a draught, which affects how you manage their day-to-day life. A small dog sweater can make a real difference for a Chihuahua on cooler days.

That said, a well-socialised Chihuahua is a genuinely joyful companion. They’re quick, clever, and absolutely hilarious to watch.

Trainability

This is where Pomeranians have a meaningful edge, in my experience.

Sash learned basic commands quickly. Pomeranians were bred to work alongside humans, and that history makes them responsive to training when it’s done consistently and with positive reinforcement. They can be stubborn — Sash will occasionally look at me as if I’ve said something deeply unreasonable — but they’re fundamentally eager to engage.

Chihuahuas are intelligent but can be harder to motivate. They’re more likely to decide that a training session isn’t worth their time, particularly if they feel the reward isn’t adequate or the relationship with the trainer isn’t solid. Both breeds respond poorly to harsh correction. The Association of Professional Dog Trainers consistently recommends positive reinforcement methods for small breeds, and I’d back that completely based on my own experience with Sash.

Housetraining is where both breeds earn their difficult reputation. Small bladders, strong wills, and a tendency to think the carpet is basically outside. Patience and routine are non-negotiable, and having a good supply of puppy training pads on hand during the early weeks is something I’d strongly recommend.

Grooming Requirements

If coat care is a dealbreaker for you, this section matters a lot.

Pomeranian Grooming

Pomeranians have a thick double coat that sheds constantly and blows out seasonally in a way that can feel genuinely alarming the first time it happens. I brush Sash at minimum three times a week using a good slicker brush, and during a coat blow, it’s daily. She also needs regular trimming around her ears, paws, and rear end to stay tidy. Professional grooming every six to eight weeks is practically mandatory unless you’re confident with a quality pair of grooming scissors and a good pet dryer.

This is the single biggest commitment Pomeranian ownership involves. If you’re considering what daily life with one of these dogs actually looks like, the guide on what to expect with a Pomeranian is worth reading before you make any decisions.

Chihuahua Grooming

Short-coated Chihuahuas need very little grooming — an occasional brush with a soft bristle brush and a wipe-down is usually sufficient. Long-coated Chihuahuas require more attention but still far less than a Pomeranian. If you want a small dog without the grooming overhead, the Chihuahua wins this category convincingly.

Health Considerations

Both breeds are generally long-lived — 12 to 16 years is typical for both — but each comes with specific health vulnerabilities worth knowing.

Pomeranian Health

• Luxating patella — the kneecap slips out of position, common in toy breeds
• Tracheal collapse — a weakening of the tracheal rings, exacerbated by collar pressure (always use a harness)
• Alopecia X — a coat condition sometimes called Black Skin Disease, more common in Pomeranians than most breeds
• Dental disease — small mouths mean crowded teeth; daily brushing is genuinely important

Chihuahua Health

• Molera — some Chihuahuas are born with a soft spot on the skull that never fully closes, requiring careful handling
• Hydrocephalus — fluid on the brain, more prevalent in apple-head Chihuahuas
• Hypoglycaemia — low blood sugar, particularly in very small or young dogs; keeping a glucose supplement recommended by your vet on hand is a sensible precaution
• Luxating patella — shared with Pomeranians and most toy breeds

Which Breed Suits Which Lifestyle?

Here’s the practical breakdown:

I’ll say this plainly: if you have the time to brush a dog regularly and you want an animated, social, trainable companion, a Pomeranian is a brilliant choice. If you want minimal grooming and a fiercely devoted one-person dog, a Chihuahua might suit you better. Neither breed is wrong — they’re just different.

Frequently Asked Questions

Are Pomeranians or Chihuahuas better for first-time dog owners?

Pomeranians are generally considered the more manageable option for first-time owners because they tend to be more eager to train and slightly more socially flexible. Chihuahuas can be more challenging due to their strong attachment behaviours and sensitivity. Both breeds require consistent training and early socialisation, but Pomeranians tend to respond more readily to positive reinforcement from the outset.

Do Pomeranians or Chihuahuas bark more?

Both breeds are vocal, but Pomeranians are typically more frequent barkers. They are alert dogs with a strong watchdog instinct, which means they’ll announce anything that catches their attention. Chihuahuas bark too, but their triggers tend to be more specific, often related to perceived threats to their person. Training and socialisation from an early age helps manage barking in both breeds.

Which breed is better with children — Pomeranian or Chihuahua?

Pomeranians generally handle family environments with children more comfortably, provided the children are taught to interact gently with small dogs. Chihuahuas can be more reactive around young children, partly due to their strong attachment to one person and their small size making them feel vulnerable. Neither breed should be left unsupervised with very young children.

How much grooming does a Pomeranian need compared to a Chihuahua?

A Pomeranian needs brushing at least three times per week, daily during seasonal coat blows, and professional grooming every six to eight weeks. A short-coated Chihuahua needs very little — occasional brushing and basic maintenance. Long-coated Chihuahuas fall somewhere in between but still require significantly less grooming time than a Pomeranian.

Do Pomeranians and Chihuahuas get along with other dogs?

Both breeds can coexist with other dogs when properly socialised from puppyhood, but both also have a tendency to forget how small they are around larger dogs. Pomeranians are generally curious and sociable with other dogs when introduced correctly. Chihuahuas can be more selective and may bond preferentially with other Chihuahuas. Early and consistent socialisation is the most important factor for either breed.
