@Holly:

Are Basenji's different from other breeds in this regard and are they sensitive to any of the anesthesia (sp?) vets use?

Yes, they are different.

Here is a previous discussion on this matter: http://www.basenjiforums.com/showthread.php?t=3401. There may be more if you do a Search.

Isoflurane is the preferred anesthetic. If your vet isn't familiar with treating sighthounds, Basenjis in particular, you might want to print out this information and take it with you. I would also recommend having a pre-surgery blood test done.

There are three core vaccines (besides rabies):

Distemper
Hepatitis (adenovirus-2)
Parvovirus

Unfortunately, some vets give a combo shot that includes coronavirus, a "not recommended" vaccine. Contact your vet before your appointment and tell him or her that you want only the DHP vaccine, not a combo vaccine that includes other stuff.

You will, of course, have to have a rabies vaccine at a later date. Have that done separately and not on the same day as other vaccines. The first rabies vaccine will probably be for a duration of 1 year, after which it will be a 3-year vaccine.

I'd recommend downloading and reading a copy of the "2011 AAHA Canine Vaccine Guidelines" the link to which can be found at https://www.aahanet.org/Library/CanineVaccine.aspx .
