Hi understand your concern too. Your baby is still very tiny. I have two females Mica and Kali. Mica was spayed at about 6 months and was just 3 pounds. Kali was recently spayed at 6 1/2 months and was 3 lbs 4 ounces. Pre-op blood work was drawn first. I had full confidence in my vet as he is a well known specialist with tiny toy dogs and especially yorkies. All of the best yorkie breeders bring their yorkies to him and highly recommend him. I agree, that one should be very cautious to assure that their vet has alot of experience with providing anesthetics to dogs that are this tiny or complications could ensue. I also agree that I have been told that Isoflourine is the safest anesthetic for these tiny babies. Our vet always keeps the females in hospital over night with IV and starts them on gastro diet the following morning. We were able to pick both of the girls up around 10:00 am the next morning once they were eating well and keeping down their food. They both recuperated remarkable well after the surgery. It was just hard watching them closely so they wouldn't over do it or start jumping up or down on things. Hope that all goes well with your babies surgery when she is ready to undergo it. Take care. Cory
