Breeding dogs

When trying to breed dogs, don't believe everything that you read.
Two summers ago, I decided to breed my female beagle "Tango". I advertised in the paper for a male stud, decided on the one I wanted as my baby's "daddy", and thought that was it.....................we put them together at the right time, and soon we would have pups. Well, it didn't quite work out that way. After numerous weekends spent at "Champs" house, still there didn't seem to be a connection made, even though Tango was in, according to the books, her prime fertile stage. Eventually I ended up leaving her at Champ's house towards the 15-18th day of her cycle (as opposed to the 12-14th day that the book suggested), and she finally did become pregnant.
Well this was a success story. Last summer I planned for the same thing to happen,
left Tango at Chesters for a full week, and there was no action at all. I became very frustrated, because still, I was assuming what the books suggested to be correct. I left her there between the 12-18th day of her cycle, when prime fertility was supposed to be occurring.
After this experience I decided on purchasing my own male dog. Not only did I want to discover what was going wrong, but decided that if I found the "right" kind of daddy for my pups it would save the frustration of trying to schedule my dogs cycle with someone else's schedule, and in the long run I'd probably be financially ahead anyways.
Then came Chester. Lovely dog, lovely temperment, and very willing participant in the fathering of puppies. I eventually discovered that Tango was fertile between the 20th and 27th day of her cycle - much later than suggested by the "experts". Go figure!
