Development – curiosities and practice
-
Yorkshire terrier – trembling in the pet is more often caused by emotions experienced rather than cold.
-
Chihuahua – even 200 g of excess weight is a serious health problem.

Dental diseases – why are they so dangerous?
Why small dogs specifically?
- 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 specifically?
- 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 specifically?
- 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 acids.
Tracheal collapse and breathing problems
Why small dogs specifically?
- thin and less elastic tracheal cartilages,
- narrow trachea 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 specifically?
- every treat is a large percentage of energy needs,
- less physical activity in practice (short walks),
- more often spoiled with "table scraps."
Effects: heart, joint, trachea strain.
Solutions: diet control, activity, light diets.
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.
