📋 Breed Predispositions

Condition	Prevalence	Onset	Severity	Screening
Gastric Dilatation-Volvulus (Bloat)	High — giant, deep-chested conformation	2-10 years	LIFE THREATENING	Discuss prophylactic gastropexy at the time of spay/neuter.
Osteosarcoma	Elevated — giant-breed risk	6-10 years	LIFE THREATENING	Radiograph any persistent limb lameness in a giant-breed dog rather than trialling analgesia first; three-view thoracic radiographs at diagnosis.
Hip Dysplasia	Elevated	1-2 years	MODERATE RISK	OFA or PennHIP evaluation by age 2. Control growth rate on a large-breed puppy diet — over-nutrition worsens expression.
Elbow Dysplasia	Elevated	5-12 months	MODERATE RISK	OFA elbow radiographs at 24 months.
Chondrodysplasia (Pyrenean Dwarfism)	Breed-specific, autosomal recessive	Congenital; disproportion evident by 8-12 weeks	MODERATE RISK	Long-bone radiographs in a disproportionately short-limbed pup.
Congenital Deafness	Elevated	Congenital	MODERATE RISK	BAER test litters where available — unilateral deafness is invisible to owners and to a conscious clinical exam.

🏥 Anesthesia Considerations

⚠ Giant-Breed Dosing and Prolonged Recovery

Dose to lean body mass, not scale weight — giant breeds are routinely over-dosed on scale weight and recover slowly. Pad thoroughly and rotate position on procedures over 90 minutes to prevent post-anesthetic myopathy. Deep-chested: offer prophylactic gastropexy at elective abdominal surgery. Plan for a long, warm, observed recovery; the breed club also reports prolonged sedation with alpha-2 agonists, so titrate rather than dosing to the label.
