Apple head vs deer head Chihuahua
These are the two head shapes Chihuahua people argue about: the apple head — rounded skull, shorter muzzle — is the show-ring look, while the deer head has a longer muzzle and flatter skull, a bit like a tiny deer. Both are Chihuahuas with the same oversized personality; neither is officially better or healthier by default.
One practical note: the shorter the muzzle, the more crowded the teeth and the fussier the breathing can be, so ask your vet what to watch for with either shape — and pick the dog, not the head.
Common Chihuahua mixes
Designer mixes get a lot of searches, so here's an honest map: a mix inherits unpredictably from both parents — no guarantees on size, coat, or temperament. If a mix catches your eye, read both parent profiles where they exist and judge the dog in front of you.

Frequently asked questions
How long does a Chihuahua live?
Typically 14–17 years. Larger individuals and lines with known health issues tend toward the lower end.
How much does a Chihuahua cost per month?
Roughly $60–$120 per month for food, routine vet care, grooming and insurance — an estimate that varies by location.
Is the Chihuahua good for apartments?
It scores 5/5 for apartment suitability. Yes — a solid apartment dog with regular walks.
Is the Chihuahua good with kids?
It scores 1/5 for kid-friendliness. Better with older, dog-savvy kids than toddlers.
Does the Chihuahua shed a lot?
Shedding scores 2/5. Minimal shedding.
Is a Chihuahua a good pet?
For the right home, absolutely: 5/5 apartment suitability, minimal exercise needs (1/5), and a 14–17 year lifespan — one of the longest in our dataset. The caveats are real though: 5/5 barking and just 1/5 kid-friendliness mean it suits quiet adult homes far better than busy family ones.
What are common problems with Chihuahuas?
Dental disease, luxating patella, and fragility from the 1–3 kg size top the list, plus the breed’s famous barking (5/5) and shivering. Most ‘problem Chihuahua’ stories trace back to owners skipping training because the dog is small. Treat it like a real dog and most problems shrink.
What are the two main types of Chihuahua?
Apple head and deer head — the apple head is rounder with a shorter muzzle and is the show-ring standard; the deer head is longer-muzzled and leggier. Both also come in smooth and long coats. Temperament and care are the same; it is purely a looks distinction.
