Temporary. Not staying.
Thanks for all the info guys! I'll pass it along!
I really was asking for a friend in Australia but I'm glad Sara asked because that really does open some possible doors since solids are harder to come by!
Just doing an AI sort of takes the "primitive" out of the equation. It isn't uncommon for dogs who had no issues getting pregnant with natural breedings needing surgical AIs. I think Shai explained it pretty well.
Another consideration is the cost involved. AIs done involving shipped semen and repro vets, surgical or not are pricey. There's a lot invested in getting puppies from the breeding and surgical gives better odds. Also because of the spacing between heat cycles, if a breeding fails you could be looking at 6-12 months before another attempt can be made. If you have a bitch who only comes in season once a year and you try your first breeding at say, 3 and get no puppies she's 4 before the next attempt and 5 by the next one after that. There's nothing wrong with wanting to tip the odds in your favor with these sorts of things,although I think natural is always preferable if possible especially for a first breeding.
Had a friend who did an AI on her bitch, I was the "helper", she had never done an AI before, and while I don't have much experience I had more than she did. She got two shipments of chilled semen, delivered a couple days apart. She had done progesterone testing prior, with our regular vet to determine ovulation.
With a little instruction from the stud dog owner, a pipette, syringe, and 30 minutes of our time we did two AI's at her house. She ended up with a pretty good sized litter for a sheltie, (7) puppies.
No surgery involved.
Edited to add: The price wasn't really much more than a normal stud fee. I think its around $200 per shipment of semen, that depends on the stud dog owner and the kit, of course, if it doesn't take then your out that money, but if a natural breeding doesn't take you're usually out "breeding fees" or boarding/travel expenses anyway.
Yeah, frozen/thawed semen is only viable for a few hours so it has to be timed perfectly. I was really surprised when they did the surgical procedure because I thought they'd go in the "back door".
Instead they made a small incision in her abdomen, and pulled out each uterine horn individually. Then the vet used a syringe to inject it directly into the uterine horns and massaged the semen up toward the fallopian tubes.
She said that they have to time it exactly which is why they do all the progesterone tests. There's about a half hour window when the eggs are nice and ripe sitting in the uterus to be fertilized, and that's when they do the surgery. With a natural breeding the semen would be waiting there ahead of time and is viable for several days to a couple weeks, but AI for frozen semen has to get it in there before the semen dies and when the eggs are ripe. She said that the eggs were being fertilized at the exact moment she was doing the uterine massage. It was fascinating.
Another reason I've seen people use fresh collected, even when the stud is on site, is to prevent spread of STDs.
