Ok this has to be one of the strangest things i have ever heard but if true could help a lot of you breeders in determining ovulation for breeding...
I was having a weird convo with my friends mother she knows a breeder and she was talking about her breeding she told me they read in a breeding book that you could do an ovulation test called a glucose fertility test what it said was..
****At the time of ovulation, Glucose is secreted into the vagina and can be detected by inserting a strip of Glucose Enzymatic test tape into the vagina, if the edges or whole thing turns green that the female will be ready to breed in 24 hours.

I looked at the book she had and it does say that

the book is
" The Joy of breeding your own show dog" by Anne Seranne I was just curious if any of you breeders have ever heard of this i don't want to look like an idiot and argue it if it's true lol
Thought this would be an interesting topic i would love to hear from you all on it
