I am glad that you are planning to have your girl spayed.
You asked for experiences and I'd like to share mine. Keisha had a litter of 11 healthy brindle and fawn pups last May. The breeder and I split everything down the middle - expenses, profit, responsibility. I am as responsible as the breeder for every one of those pups for as long as they live. I have to be willing to take in any one of them, at any time, if needed, for whatever reason.
If I didn't have Keisha's breeder choose the stud - I wouldn't have known what to look for as the best match for Keisha. I had considered whelping the puppies at home vs. the breeder whelping and keeping the puppies for the first 10 days, until there was less risk of problems. I asked for advise on this board and the response was overwhelming in favor of taking Keisha to the breeder to whelp the pups. I am SO glad that I took their advise.
When Keisha's first pup was born it looked dead to my daughter and I. The breeder said - it's alive - but we thought that she was just saying that to calm us down. If the breeder wasn't there to revive that pup I wouldn't have known what to do, and that pup (a beautiful, spunky, little flashy brindle girl) would have died, I am sure of it. There were a few pups that needed a bit of help - though all 11 were healthy and strong. It makes me shudder to think that had I whelped those pups myself there would have been at least one pup die and it would have been my fault.
When the pups did come to stay with us at 9 days old, there was bottle feeding, changing the dirty newspapers in the box(we had to raid recycling boxes to keep up with the demand for newspaper LOL), caring for the tails, wipeing their little bums clean, making sure that all the pups had full tummies and that all teats were emptied (they had their favorite teats and I had to hold them on the less popular teats so that the milk didn't go sour etc). In the middle of the night if they cried I had to get up and see if everyone was alright. And that is just the BEGINNING. I was a nervous wreck, I was tired, and my back ached from constantly bending over looking after the pups and wipeing up Keisha's drips (she bled for approx. 11 weeks afterward). Thank god I had the breeder to call when I was worried about something.
All in all though it was a good expereince - no fatalities, mom and pups all healthy, and we kept a pup (Travis).
Having a litter of puppies is a HUGE responsibility and ALOT of work. I am thinking of breeding Keisha again, and if I do I will send her back to the breeder again for breeding and whelping. There are too many things that can go wrong, and if something were to go wrong I want my dog to be in the best hands possible. But I am having second thoughts too as it is so much work (and worry) and I had to put my life pretty much on hold for a few weeks.
I really am glad that you are now planning to have your girl spayed - I'm sure you are making the right decision.
