Could you elaborate on what infections an in season bitch would be more at risk for than one not in season other than pyo?
I am no vet so i am fairly sure i do not know the names of many infections. But i do know that a bitch can pick up what at first can be a fairly non-threatening bacterial infection which can then lead to pyo if not treated. Why risk that?
After a very brief google search i found this article by someone who, i believe, is a vet, and talks about a number of bacteria and why they believe bitches in season shouldn't be shown (it also related to puppies and mating but im sure some in-season bitches that are shown will be mated also):
And this one about an infection i've not heard of that sounds serious, like Toxic Shock Syndrome in people:
Important risk factors in the transmission of CSTSS seem to be:
Crowded conditions, such as racing Greyhound kennels and conformation dog shows, especially inside and in the fall and winter months. Conformation dogs are at higher risk than dogs entered only in performance events.
Hygiene factors, including sharing food and water bowls. Handlers and judges may transmit the infection by examining/handling multiple dogs sequentially without washing their hands. Equipment, such as muzzles used in racing dogs should be kept clean and/or not shared by multiple dogs.
Close physical contact: Although "social sniffing" and running with an infected but asymptomatic dog is reasonably safe, jaw-wrestling and play-fighting is not. Sharing a run with an infected dog is an important risk factor, as well as water-bowls, bedding, etc. Crate-swapping and sharing is high risk. Licking of genitalia of bitch in season by infected male is another high risk factor. Dogs kenneled in adjacent runs are not at high risk. Dogs licking the face of a human with a "strep throat" or cellulitis or of a child with impetigo are definitely at risk._
Im sure theres much more to be found with some digging but im at work so dont have time lol
You never know what infections and diseases other dogs may have, and in season bitches are more at risk of picking up infections so that is my reason for not showing them, or walking them where other dogs may be/at busy times etc
