In reality, as has been said, multiple factors are at play here, from the viability of the semen at the time of thawing, to the bitches viability when it comes to producing (IMO, one should breed a bitch natural before doing a frozen, just to know if she's a good producer, it lessons the waste of possibly invaluable genetic material, especially if you don't have a lot of his collection left).
Thanks for more input! She has been bred before.

I would think it's a gamble, but they are improving things all the time. We were talking about this last night, as my local studmuffin options are quite limited, so if it's reasonable to import pupcycles, I'll be doing that most of the time. Doing a natural breeding the first time round of course, but then may end up doing long distance relationships. VERY tempted to import a nice border collie boy to have on hand too, after all the headaches!

Garnett is from a litter produced from chilled semen shipped from Missouri to Connecticut, and he came from a litter of only four, which is small for Walkers. The bitch's one previous litter was much larger,in the double digits, from live cover.

And he seems really, really big to me- 10 weeks and 25 lbs, which I suspect is a result of the small litter size, but don't know for sure

This.

Kaia was surgically inseminated with frozen stuff from a long dead dog.

The vet looked at the semen under microscope when it thawed and was dismayed to see it was only 30% mobile. Which is very poor. At that point we had to do the surgery or lose the chance forever because that was his last straw, and she had a one hour window of fertility, and it was already thawed.

She had 10 puppies. 9 live births. 1 miscarried about 25 days into the pregnancy for unknown reasons. The live ones were all huge and healthy and beautiful and marvelous, so it was totally worth it.

It's worth noting that our repro vet is considered one of the best canine repro vets in the country. She's seriously amazing. I'm convinced the only reason Kaia conceived so many is because of the vet's spidey sense for ovulation timing.

Yes, timing is key, and a good repro vet. Tully's breeder has also had good success with frozen semen. She's used trans-cervical insemination, but I brought that up to the vet I was using, and he preferred to go with surgical. I thought it best to go with what the vet was comfortable with, to get the best possible results.

Tully's breeder did bring up that maybe I should try a live cover breeding first, after Tully's sister had some reproductive difficulties, but my feeling was that I really only wanted to breed her once, and didn't want to pop out puppies just to pop out puppies; if I produced puppies, I wanted to know that I was aiming at perfection. So I chose to take the gamble of frozen semen on a maiden bitch. (it also was far from the last straw from that stud, and he'd produced other litters, so it wasn't a matter of using it up and losing all chances at that genetic material).

While I was sorry to lose the other 5 puppies, I did get Tess out of the breeding, and she is rather exceptional. And she has produced Pirate, also exceptional. So... probably worth it.

Nel's last season, we had a TCI done with frozen pellets. Got a great repro vet, progesterone tested her, but unfortunately the storage facility that had handled the dog had either incorrectly labeled or... well basically everything went wrong. When thawed it was between 30 and 50% motile, diluted to half the concentration it should have been, was tinted pink (blood present), and they sent one breeding dose when we asked for two. Needless to say the pregnancy didn't take. Was heartbreaking but all in all, I kind of expected it.

She just came into season again on Tuesday and went for her first progesterone test today. We're using a different dog this time, 80% motility but frozen once again.

A TCI is trans-cervical insemination, for those who haven't heard of it. It uses a kind of catheter and a fiber optic scope to inject everything through the cervix into the uterus. Minimally invasive and doesn't require sedation, but it does require an experienced repro vet who has an eye for timing.

We have a much better shot this time, but she's never been bred naturally, which I have heard reduces chances it will take. Her sister had 6 puppies through a TCI with frozen and she and her sister came from a litter of 11 produced through a TCI with frozen. The dog has produced litters with frozen, including the current #7 Dane in breed standing (woot!) so I'm trying to stay hopeful this time.
