Section 5. Bitches In Season. Bitches in season shall not be eligible for entry in any Hunting Test and shall not be allowed on the grounds. Entry fees paid for a bitch withdrawn because of coming in season or for a dog withdrawn because of an injury or illness, or for a dog that dies, shall be refunded in full by the test-giving club. Prior to paying such refund, the club may require an appropriate veterinary certificate. In the event a dog is withdrawn for other reasons, the test-giving club is free to formulate its own policy with reference to refunds provided that said policy shall be fixed in advance of the mailing of the premium list for any particular Test.
