Our Little Chafuko had a surgery a couple of months ago, We were so afraid of the risks and talked about it with our Vet.
He did also some recearch by himself and decided (with us) to give a anhestetic for a sighthound, we stayed during te beginning for (maybe upcoming stress) and the vet started with a little ammount till he got to sleep. He held him to sleep with special gas, so he could wake him up if neccesary, or give him more or less gas.
There also was during the whole surgery an assistant for Chafuko wich checked him the whole time.
It all ended very good, he didn't get any bad results from the anestetics…
This vet is fascinated bij Basenji's and is a real fan of our B's. I also worked there as a veterninairy assistand so i know them personally.
This is al happened at our place in the Netherlands, i don;t know how it is and what the vets use at you place.
But it's important to talk with your vet and tell him the risks..
If it's a good vet, he will listen and look for a right anesthetic
