What the bill actually looks like — line by line, by state tier, and with pet insurance applied. Updated August 16, 2026 · Allen Lee, Founder, Best Dog Insurance.
BOAS surgery for a French Bulldog costs $3,000–$5,500 nationally for a full airway correction, and $4,500–$6,800 in high-cost metros. A nares-only procedure on a mild case runs $500–$1,500. With 80% reimbursement after a $500 deductible, insured owners typically pay $1,000–$1,600 out of pocket.
BOAS is rarely one procedure. Surgeons correct every obstruction found in a single anesthetic event, so the invoice stacks: pre-surgical exam and airway scoping $150–$450, bloodwork and imaging $200–$600, soft palate resection $800–$1,800, stenotic nares widening $500–$1,200, everted laryngeal saccule removal $300–$900, anesthesia and monitoring $500–$1,200, overnight oxygen observation $300–$1,000, and medications plus rechecks $150–$400. A full correction totals roughly $2,900–$7,550.
Cost by state tier: high-cost metros in California, New York, Massachusetts, and Washington run $4,500–$6,800; the national average is $3,000–$5,500; lower-cost states such as Mississippi, Arkansas, West Virginia, and Kentucky run $2,200–$4,000. Nares-only correction on an early, mild case costs $500–$1,500 and is often done at the same time as spay or neuter.
Signs that push owners toward surgery include snoring or snorting while awake, gagging or retching after eating, tiring after five to ten minutes of walking, blue-tinged gums or collapse in heat, and sleeping with a toy in the mouth to hold the airway open. Veterinary surgeons generally recommend correction between 6 and 24 months of age, before chronic airway strain causes laryngeal collapse.
Pet insurance covers BOAS as a hereditary condition when the dog is enrolled before any breathing complaint appears in a vet record. Reimbursement is 70–90% after the deductible, hereditary waiting periods of 6–12 months apply on some plans, and a $10,000 or unlimited annual limit is the safe target for a Frenchie.
Recovery: most dogs go home within 24–48 hours, eat soft food and stay leash-only for one week, and return to short walks over weeks two to four with a harness instead of a collar. Untreated BOAS progresses to laryngeal collapse, heat-intolerance episodes, and aspiration pneumonia, with emergency visits costing $1,500–$4,000 each.
Yes. Accident-and-illness plans cover BOAS as a hereditary condition provided the dog was enrolled before any breathing symptoms were noted in a vet record. Reimbursement is typically 70–90% after the deductible, and some plans apply a 6–12 month hereditary waiting period.
Most corrections combine soft palate resection, stenotic nares widening, and removal of everted laryngeal saccules in one anesthetic event. Bloodwork, anesthesia, monitoring, and overnight oxygen observation are billed separately.
Between 6 and 24 months in most cases, before chronic airway strain causes laryngeal collapse. Early nares widening at spay or neuter is cheaper and lower risk.
Most French Bulldogs go home within 24–48 hours and are restricted to leash-only activity, soft food, and a harness for two to four weeks. Breathing usually improves within days.
Untreated BOAS progresses to laryngeal collapse, heat-intolerance episodes, and aspiration pneumonia. Emergency visits cost $1,500–$4,000 each, so early correction is usually cheaper over a Frenchie's lifetime.
