Development – curiosities and practice
-
Yorkshire terrier – trembling in your pet is more often caused by emotions experienced rather than cold.
-
Chihuahua – even 200 g of excess weight is a serious health problem.
-
Maltese – white fur stains easily, requires daily hygiene.
-
Shih tzu – large, beautiful eyes are easily damaged and infected.
-
Cavalier – heart ultrasound is a mandatory test after 5 years of age.
-
Jack Russell – an unexercised dog releases energy by destroying furniture.
Dental diseases – why are they so dangerous?
Why small dogs in particular?
- they have tightly packed teeth in a small jaw,
- saliva has a different pH than in large dogs – tartar builds up faster,
- the miniature jawbone easily atrophies during inflammation.
Consequences: from tooth loss to endocarditis.
Prevention: brushing, dental chews, dry food.
Joint problems and patellar luxation
Why small dogs in particular?
- thinner and more delicate bones,
- weaker ligaments and muscles,
- every jump (e.g., from the couch) is proportionally a big strain.
Consequences: jumping on three legs, lameness.
Prevention: limit jumping, weight control, strengthening exercises,
joint-supporting food.
Heart diseases – what to watch out for?
Why small dogs in particular?
- faster heart rate (up to 160/min) = greater valve strain,
- smaller heart structure,
- genetic predispositions (e.g., Cavalier).
Consequences: night cough, quick fatigue, shortness of breath.
Prevention: heart echo, diet with omega-3 fatty acids.
Tracheal collapse and breathing problems
Why small dogs in particular?
- thin and less elastic tracheal cartilages,
- narrow tracheal diameter – easily compressed,
- genetic predisposition of Yorkshires, Maltese, Chihuahuas.
Symptom: characteristic "goose honk" cough.
Prevention: harness instead of collar, proper weight.
Obesity – the biggest enemy of small breeds
Why small dogs in particular?
- every treat is a large percentage of energy needs,
- less physical activity in practice (short walks),
- more often spoiled with "table scraps."
Effects: strain on the heart, joints, trachea.
Solutions: food control, activity, light foods.
Coat, ear, and eye care
Neglected coat = allergies, infections, mats.
- long-haired dogs = daily brushing,
- Cavalier and shih tzu = frequent ear checks,
-
Maltese and shih tzu = daily eye cleaning.
Psychology of a small dog – separation anxiety
Small dogs form strong attachments. Loneliness = barking, destruction, apathy.
Solutions: interactive toys, independence training, kennel crate.
Annual prevention and vaccination plan
- Every 3 months: deworming, tick prevention products.
- Every 6 months: dental check, general examination.
- Once a year: vaccinations (distemper, parvovirus, rabies), heart echo, blood tests.
- Daily: coat, eye, and ear care.
Essential accessories for the health of small dogs
- Harnesses – protects the trachea.
- Slow feeder bowls – prevents choking.
- Cooling mat – especially for brachycephalic breeds (shih tzu).

Kennel crate for dogs
FAQ – unusual questions
Why does my York shake when happy?
It’s emotions, not cold – typical for this breed.
How to distinguish cardiac cough from tracheal cough?
Tracheal – dry, “goose”; cardiac – at night, after exertion.
Is a Jack Russell suitable for apartment living?
Yes, but it requires intensive walks and mental training.
Why does a Maltese have reddish stains under the eyes?
This is a result of tearing – requires daily hygiene.
Summary
Miniature dogs bring great joy but also big challenges. Their body structure makes them more prone to problems with teeth, joints, heart, or trachea. The key to health is awareness of anatomical differences, regular prevention, and a tailored diet.
