thank you for this. I am not angry, but I am a bit frustrated.
I just don’t see why you can’t see that your questions don’t really make sense, since antibiotics are really only a short gap measure, used to stabilize a very sick bitch before she can get into surgery or for a valuable breeding bitch in the HOPES of preserving her life and fertility until she can produce another litter, a bitch who will very likely eventually need surgery anyway.
the bitch in question here would be (as stated earlier by the OP) stable enough to spay quickly and she is not a valuable breeding bitch. She’s a 10 year old beloved pet. There is not a good reason to pursue the antibiotics route unless the OP is already looking toward her next bitch, who from previous posts in the thread, will also be a beloved companion and not a valuable breeding bitch. After all, if the OP has to have time to get the monies for this spay together, the OP will not have the cash to buy a truly outstanding example of any particular breed in future either.
I certainly believe Marshfield when she says the cost of such a protocol is comparable to an emergency spay. The dog might very well require hospitalization to monitor the infection in case it closes off and the danger of sepsis becomes immediate and very real.
and anyone who has a valuable bitch would do that. They probably would have the cash in reserve or a card just for use with the dog(s).
The overwhelming odds are your dog will be fine with getting spayed. I can even relay an experience of a dog that was spayed at later in life: my family’s Cairn Terrier, who was spayed at 9 1/2 years and at the vet’s suggestion to avoid pyometra and other problems.
as I stated earlier, I know 3 bitches who developed pyos and had the emergency spay surgery. All of them came through fine.
Thank you grayarabpony, for a thoughtful reply to the OP
