Hi. I just got back from the vet. I talked about yuna getting spay and he recommended spaying before the first heat so that's probably around 6 months or so. I was wondering what you guys did with your furbabies. She is 4 months old at 4.67lbs and he said she has 12 permanent teeth already. I asked about the tube they use and he said he uses human baby tubes. I read on another post that someone thinks the tubing has caused collapsed trachea for their furbaby. Also, I was wondering what anesthesia he should be using. He seems to have a lot of large dogs as patients (at least from what I have seen) so I don't know if I should find a vet that commonly does spays for small dogs.
