There's a vet in Campbellville (Milton area) that sees a lot of bulldogs and might be worth looking into. Ask for Dr. Ball though, he owns the clinic and has far more experience than the other vets.
Brookville Veterinary Clinic
RR#1 Campbellville, Ontario
Phone: (905) 854-2216
Fax: (905) 854-1169
I found him by emailing the Bulldog Club of Central Canada. Maybe email the club too to see if there are other specialists in the area.
Good luck in your search, I know we always want to find the best for our bullies. Stig and I will be thinking of you both.
