Miniature Schnauzer Health Testing Requirements for Stud Dogs

Miniature Schnauzers are lively, intelligent terriers with a distinctive beard and eyebrows — and a set of inherited health concerns that require comprehensive testing before breeding.

The American Miniature Schnauzer Club (AMSC) participates in the OFA CHIC program.

CHIC Requirements for Miniature Schnauzers

• OFA Eye Examination (CAER)
• DNA test for Progressive Retinal Atrophy (prcd-PRA)

Progressive Retinal Atrophy (PRA)

prcd-PRA is the most important genetic disease in Miniature Schnauzers. Autosomal recessive — Carriers are healthy and can be bred to Clear dogs safely. All stud dogs should be DNA tested.

Primary Lens Luxation (PLL)

PLL causes the lens to displace, leading to glaucoma and blindness. DNA testing for the ADAMTS17 mutation identifies Clear, Carrier, and At-Risk status. Mini Schnauzer carrier frequency is significant — testing is strongly recommended.

Hereditary Cataracts

Hereditary cataracts occur in Miniature Schnauzers. CAER eye examination is the primary screening tool; DNA testing for some variants is available.

Pancreatitis

Miniature Schnauzers have the highest documented pancreatitis risk of any breed. Hypertriglyceridemia (elevated blood fat) is common in the breed and predisposes to pancreatitis. While no DNA test exists, diet management and selecting against affected pedigrees is important.

Mycobacterium Avium Complex (MAC)

An immune deficiency causing fatal mycobacterial infections, unique to Miniature Schnauzers. DNA testing is available; this is a rare but serious condition.

Summary

A responsible Miniature Schnauzer stud dog should have: OFA CAER eye exam, prcd-PRA DNA testing, PLL DNA testing, and MAC DNA testing. Pancreatitis history in the pedigree is relevant context. PLL and prcd-PRA together represent the primary genetic threats to vision in this breed.
