My vet clinic has evolved from small to large and in the process seems to be more expensive. Arlie, as some of you may recall, had an anal gland "episode" recently. I paid for a recheck exam for her, mainly because one of her teeth needed looking at, plus $38 and change to have her anal glands expressed. This process took minutes and as a bonus for some reason didn't even smell all that bad. It seemed like a lot to me on top of the exam fee is $58. In other words, about $100 to examine the tooth and express the anal glands. Nail clip with exam is$12 and change.
On the other hand, I paid a special fee to have Rickie's eye examined (forget what it was) but because his problem was hard to find (impossible in fact) the vet must have spent at least 30 minutes checking him out. This was in addition to the exam fee, but may have been less than the anal glands, go figure.
Net: for 2 dogs to have their nails clipped, for Rickie an extensive eye exam (staining, the works), for Arlie a tooth check, plus anal gland check / expressed was $200 (and I get a multi-pet discount because I have 3 pets - the third is a cat).
No idea how this compares generally.
Edited to clarify Arlie's exam was a recheck to ensure the anal glands weren't "brewing" again and a few other details.
