It depends on which type of implant you're talking about and the knowledge and ability of who is doing the timing and implanting. I'd do trans-cervical over surgical any day. I avoid anesthesia wherever possible, plus, wherever you have scaring in the uterus, (i.e. from a prior c-section), a placenta can't attach, so, even though surgical implantation leaves a tiny, tiny scar, you never know if additional scar tissue will develop and since trans-cervical is available, I'd prefer not to take the chance. Kathy ================================================================ It also depends of whether you have a good repro vet available. I have done three implants. First one about six years ago was done surgically and with freshly chilled semen. I had to travel five hours to get to this vet who was very good but did not feel comfortable with transcervical implanting (it was a fairly new technique then). She did the surgical implant and an AI two days later - I had seven puppies. A year ago, I tried again and it was a disaster. There are no local vets who do expert repro work. My regular vet did a surgical implant - she does not know how to do transcervical. It was in the middle of an ice storm and I had to drive to the airport because UPS would not guarantee delivery of the sperm package. I found out later that the dog was having fertility problems and I had no puppies. I don't believe it had anything to do with the procedure but with the dog itself. Last time I drove three hours to a repro expert - what a difference. He actually knew what the heck he was doing. HALLELLUJAH!!!! I had a transcervical implant - great technique. Results: nice healthy litter. If you have a good vet in your area... Be nice to him... He is worth his weight in gold.
