Required vaccinations for all dogs, including dogs not racing: distemper, adenovirus-2 (respiratory + hepatitis), parvovirus, rabies and kennel cough (parainfluenza + bordetella bronchiseptica).
All vaccines must have been administered more than 21 days before the race. The validity will be the one the laboratory advised (meaning sometimes 3 years validity for the other vaccines, but 1 year for kennel cough). For kennel cough, both intranasal and injection will be accepted. If you use an intranasal form, it is advised (but not mandatory) to have a boost less than 6 months before the race.
