Chihuahuas have a reputation for being snappy, yappy and difficult. A significant proportion of that is created rather than inherited, and the cause is consistent: they are treated as accessories rather than as dogs.
The core problem
Rules that would be enforced with a Labrador are waived for a 2kg dog. Nobody trains a recall, nobody socialises them properly, nobody teaches them to walk on a lead — because you can simply pick them up.
And being picked up constantly, without warning, by people the dog does not know, is genuinely frightening for an animal that small. A Chihuahua who snaps at approaching hands has usually learned that hands mean being seized and lifted.
Treat them like a dog:
- Socialise thoroughly, before 16 weeks
- Teach a recall
- Teach loose lead walking
- Let them walk
- Ask before picking them up — teach a “up” cue so it is predictable
- Enforce the same rules you would with a big dog
Do those things and most of the stereotype disappears.
Socialisation, specifically
The world is genuinely more threatening at that size. Everything is larger, faster and higher, and a stumble from a person is a serious event.
Socialise carefully rather than less:
- At their level. Sitting on the ground, letting people approach low and slowly
- With appropriate dogs — calm, small or medium, not boisterous. A well-meaning Labrador puppy can injure a Chihuahua without any intent
- Handling practice, so being picked up, held and examined is familiar and predictable
- Never force an approach. A frightened small dog has very few options
Health
Dental disease. The most consequential. A full set of teeth in a tiny jaw means crowding, retained baby teeth, and early periodontal disease.
Brush several times a week, from puppyhood. Chihuahuas frequently need dentals from a young age, and the anaesthetic risk in a very small dog is not trivial, so prevention matters.

Virbac C.E.T. Enzymatic Toothpaste
An enzymatic paste most dogs accept as a treat. Introduce it over two weeks — paste on a finger first, then a brush — and it becomes routine rather than a fight.
Patellar luxation. Very common. The characteristic sign is a skip for a few strides with one back leg held up, then normal walking.
Tracheal collapse. A honking cough, triggered by excitement or pressure on the neck. Always a harness, never a collar.
Hydrocephalus, associated with the open fontanelle (moleras) that many Chihuahuas have. A soft spot on the skull is normal in the breed; a dome-shaped head with neurological signs is not.
Hypoglycaemia in puppies. Very small puppies can crash their blood sugar. Frequent small meals, and keep glucose syrup in the house — weakness, wobbliness or collapse needs syrup on the gums and a vet.
Heart disease, particularly mitral valve disease with age.
Eye injuries. Large prominent eyes close to the ground. Any squinting or redness is a same-day visit.
Cold intolerance. High surface area to volume ratio and very little insulation. A coat in winter is function, not fashion.
Obesity, which in a 2kg dog happens on remarkably little extra food.
Feeding
The margins are tiny. A 2.5kg dog needs a genuinely small amount of food, and half a biscuit is a meaningful share of it.
- Weigh the food. Scoops are hopeless at this scale
- Count every treat
- Feel for ribs monthly
- Two to three small meals a day
- Watch for hypoglycaemia in puppies and very small adults
Outward Hound Fun Feeder Slo Bowl
Choose a small, shallow-pattern bowl. Making a very small measured portion last several minutes is most of how a tiny dog’s weight is held steady without either party feeling short-changed.
Exercise
More than people assume: 30 to 60 minutes a day, split, plus mental work.
They are not ornaments. A Chihuahua who is carried everywhere becomes under-exercised, over-aroused and increasingly reactive.
On the ground, on a lead, walking. With a harness.
rabbitgoo No-Pull Dog Harness
Adjustable, which matters enormously at this size where standard sizing rarely fits. A harness rather than a collar is not optional for a breed prone to tracheal collapse.
Mental work matters as much as the walk — scent games, puzzle feeders and training.
Training
Clever, food-motivated, and entirely trainable. The obstacles are practical:
- Get down to their level. Training a dog whose head is 20cm off the ground while you stand over them is unpleasant for both of you
- Use tiny treats. Pea-sized is too big — a grain of cheese is about right
- They cannot hear you well from up there. Hand signals help
- Short sessions
Priorities:
- Handling and being picked up, on cue
- Socialisation
- Recall
- Loose lead walking
- Barking management — block the view, train a mat cue for the doorbell, and address the underlying arousal
House training is often slow. Small bladders, a dislike of cold and rain, and owners who do not notice a small puddle quickly. Be patient, use a schedule, and consider a covered outdoor area.
Grooming
Two coat types.
Smooth: a rubber curry mitt weekly. They shed more than you would expect.
Long: brush two or three times a week with a pin brush and comb, paying attention to the feathering on the ears, legs and tail.
Both: nails every two to four weeks, ears weekly, teeth several times a week.
Safety around the house
Genuinely worth thinking about at this size.
- Being trodden on or sat on
- Being knocked down stairs
- Jumping off furniture — patellas and legs
- Larger dogs, even friendly ones
- Birds of prey, in rural areas, which is not as far-fetched as it sounds
- Cold and wet
Who they suit
People who want a genuinely portable dog and will still treat them as a dog. Older owners, flat dwellers, and households without very young children.
They do not suit families with toddlers, people who want to carry a dog rather than walk one, or anyone expecting a small dog to be low-effort.
The honest summary
A well-socialised, properly exercised, ground-dwelling Chihuahua who has been taught to walk on a lead and to expect handling is a confident, funny, affectionate little dog with none of the reputation.
The reputation exists because most of them are not given that.
