The Maltese is small in size but big in personality. However, small breeds have their own expensive problems - dental disease, kneecap issues, and heart conditions are the hidden costs of compact dogs.
Measured risks
How often they happen is backed by published studies.

All dogs General canine obesity prevalence; no Maltese-specific breed effect confirmed.
Up to 40% of adult dogs are overweight. Obesity accelerates joint deterioration, increases cardiac load, and shortens life expectancy by 1-2 years. Full profile →

All dogs All-dogs baseline skin disorder rate; no Maltese-specific breed effect confirmed.
Chronic skin allergies. Full profile →
Known risks
Well documented in the breed - but no study has counted how often.

Not measured Maltese is confirmed absent from the landmark O'Neill et al. 2016 VetCompass patellar luxation study - no real breed-specific figure exists. OFA screening database: 4.8% of 1,876 submitted patella exams graded abnormal. Voluntary submissions - true population rate may differ.

Not measured Maltese is confirmed absent from the O'Neill et al. 2021 JSAP periodontal disease breed table - despite the breed's popular reputation for dental problems, no real breed-specific figure was found in this study.

Not measured Only case reports and small referral-hospital case series exist (idiopathic tremor cases made up ~24.7% of tremor cases at one hospital). No population-level prevalence data exists for Maltese specifically, and the condition is now recognized as not truly breed- or coat-color-specific.
A sudden-onset generalized tremor disorder historically named for small white breeds like Maltese, though the cause remains unknown. Full profile →

Breed study [1] 14 of 62 dogs (22.6%) with surgically-confirmed congenital portosystemic shunt at one referral center over 15 years were Maltese - described as significantly overrepresented (Tisdall et al. 1994, Australian Vet Journal). This is a referral case-series overrepresentation, not a general-population prevalence rate.
Maltese is one of the breeds most overrepresented in liver shunt surgical case series, though true population prevalence is unknown. Full profile →
How we know these numbers
- Confirmed = measured or gene-confirmed specifically in this breed
- Breed study = scientists counted it in this exact breed
- Body type = comes from the dog's build - size, skull, skin
- Genetic risk = the gene is proven, the odds are not
- All dogs = an average for all dogs, not this breed
- Not measured = nobody has counted it yet
- How we grade evidence →

My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
