Update
My dog went into heat Wednesday, I decided to use the vet, she had her second treatment on Friday. The vet said not to bring her in until Monday unless they were showing more interest as she did a smear that showed she is was only 20% into her heat (a heat can be all over in 2 days or drag out weeks so it is very hard to pinpoint the best peak time to AI).
Anyway...Sunday morning arrived and Chip is more interested in the girl in the next dog run and sure enough she is in high heat. So my vet took them all in on Sunday and we are trying with both girls. This is Chips third year with me with no pups from him either naturally or with the two AI attempts we had previously tried; this is the very last attempt to have pups – I could be in a sea of three litters puppies at the end of June as two of my other dogs were doing what comes naturally the past two days.
After more than a year since my only litter of pups was born last year, you can imagine how exciting this is.
