The Bottolo is considered a generally healthy breed with a life expectancy of twelve to fifteen years, a respectable span that reflects the relatively low incidence of severe inherited conditions compared to some other purebred dogs. The breed's small gene pool, a consequence of its near-extinction after World War II and its continued rarity outside of Italy, means that responsible breeding practices are essential for maintaining the population's overall vigor. Prospective owners should seek breeders who conduct health testing and can provide documentation of screening results for both parents.
Patellar luxation is the most commonly reported orthopedic issue in the Bolognese, as it is in many toy breeds. This condition occurs when the kneecap slides out of its normal groove in the femur, causing the dog to skip, hop, or carry the affected leg temporarily. Mild cases may require only monitoring and weight management, while more severe grades can cause chronic pain and lameness that necessitate surgical correction. The American Bolognese Club recommends patellar evaluation as part of routine health screening for breeding stock, and buyers should ask breeders about the patellar history in their lines.
Legg-Calve-Perthes disease is another condition that appears in toy breeds including the Bolognese, though it is not as frequently reported as patellar luxation. In this condition, the blood supply to the head of the femur deteriorates, causing the bone to weaken and collapse. Affected dogs typically show signs between five and twelve months of age, presenting with hind limb lameness and pain during hip movement. Surgical removal of the damaged femoral head is the standard treatment and generally produces good functional outcomes, allowing the dog to return to normal activity.
Eye conditions including progressive retinal atrophy and cataracts have been documented in the breed. PRA causes gradual deterioration of the photoreceptor cells in the retina, leading to progressive vision loss that typically begins with reduced night vision and advances to complete blindness. Genetic screening tests are available for some forms of PRA, and responsible breeders test their dogs before breeding. Cataracts can develop at various ages and may be hereditary or age-related; regular eye examinations by a board-certified veterinary ophthalmologist help detect these conditions early when management options are most effective.
Periodontal disease is a significant concern for the Bolognese, as it is for virtually all toy breeds. The breed's small jaw and correspondingly crowded dentition create conditions where plaque and tartar accumulate rapidly, leading to gum inflammation, tooth root abscesses, and premature tooth loss. Daily tooth brushing, dental chews, and professional cleanings as recommended by your veterinarian form the foundation of dental health maintenance for this breed. Left unaddressed, advanced periodontal disease can affect not only the mouth but also the heart, kidneys, and liver through bacterial spread into the bloodstream.
Common Health Issues
- Patellar luxation - A common orthopedic condition in small breeds where the kneecap slides out of its normal position in the groove of the femur, causing intermittent lameness and discomfort; severity ranges from occasional slipping that self-corrects to chronic displacement requiring surgical intervention.
- Legg-Calve-Perthes disease - A painful condition in which the blood supply to the head of the femur deteriorates, causing the bone to weaken, collapse, and eventually lead to arthritis of the hip joint; typically appears in puppies between five and twelve months of age and often requires surgical removal of the damaged femoral head.
- Progressive retinal atrophy (PRA) - A group of inherited degenerative eye diseases that cause the photoreceptor cells in the retina to deteriorate over time, leading to progressive vision loss and eventual blindness; genetic screening tests are available and responsible breeders test breeding stock before mating.
- Cataracts - Opacity of the lens of the eye that can develop at various ages and may progress to significant vision impairment or blindness; hereditary forms can appear in younger dogs while age-related cataracts are more common in seniors, and surgical removal is the primary treatment option.
- Periodontal disease - Small breeds like the Bolognese are particularly susceptible to dental disease due to crowded teeth in a compact jaw, leading to accelerated tartar buildup, gum inflammation, tooth root abscesses, and premature tooth loss without consistent preventive dental care.
- Hip dysplasia - While less common in toy breeds than in larger dogs, the Bolognese can develop malformation of the hip joint where the femoral head does not fit properly into the acetabulum, leading to pain, reduced mobility, and progressive arthritis; screening of breeding stock helps reduce incidence.
Preventive Care & Health Monitoring
- Annual veterinary eye examination by a board-certified ophthalmologist - The American Bolognese Club recommends routine eye screening to detect early signs of progressive retinal atrophy, cataracts, and other hereditary eye conditions before they progress.
- OFA patellar luxation evaluation - Veterinary examination of the stifle joints to assess kneecap stability, with results registered through the Orthopedic Foundation for Animals; recommended for all breeding stock.
- Daily dental care including tooth brushing - The Bolognese's small jaw and crowded dentition make daily brushing essential to prevent the rapid tartar accumulation and periodontal disease that commonly affect toy breeds; professional dental cleanings should be scheduled as recommended by your veterinarian.
- Weight management through portion control and regular monitoring - Even a single extra pound on a dog this small places significant stress on joints and organs; maintain a visible waist and palpable ribs through measured feedings and limited treat intake.
- Regular ear cleaning and inspection - The Bolognese's floppy, heavily coated ears trap moisture and debris, creating conditions favorable for bacterial and yeast infections; weekly cleaning with a veterinarian-approved ear solution helps prevent problems.
- Request health testing documentation from breeder for both parents - Responsible breeders should provide evidence of eye examinations, patellar luxation evaluations, and any available genetic screening results for both sire and dam before placing puppies.
