Probing and Popping are basics so if a vet told me they did not, I would be a little suspicious regarding the so called knowledge. If you go there and ask to have your snake probe they should do it (for a fee of course)
I have said this before but a vet near me who claims to see exotics and snake in particular diagnosed one of my friend's snake with septicemia when the animal was going through shed
Not all vet are honest, pretty much like in any profession there are the good ones and bad ones and those that will make it sound like they have experience when they do not and most of the time it works until they meet with an owner that has more knowledge than they do.
If you don't have the knowledge I am fine with that I just want honesty, my vet is honest I actually am the one that taught her how to sex a snake.
So yeah "we deal with reptiles" does not mean much those days, they deal with everything the real question is do you have some serious hand on experience.
