Its one procedure, not two. Couple of words of wisdom:

1. Use a young bitch. Old bitch with frozen semen is like shooting pool with a rope.
2. take your bitch for the first time on day 11. I've never had a bitch too late. If shes under a 2.00 , go back in 4 days not two. if shes at a 3, take her back in two days.
3. use a Trans cervical procedure drops the semen on the egg with a small camera. I like it better than surgery
