Could someone tell me more about this class or where I can find out more. I have a 5 month old that I would like to enter but did not find anything on age or if it is all one class. Or do they do a bitch and dog? TIA

If you are asking about Bred By in AKC shows, you can see all the requirements on the AKC site under Dog Shows, rules and regulations....they have the entire rule book in pdf.

The dog or bitch must be older than 6 months, been bred and is owned (or co-owned) by the breeder to be eligible.

You might be better off entering your pup in the age appropriate puppy class (6-9 month, 9-12 month, 12-18 month) and then switch over to Bred by Exhibitor when they hit 18 months of age. If you start showing a 6 month old in Bred By the puppy may look a little too young when being compared to adults.
