"I would like an appointment today for my dog"
"sorry we don't have any openings today, is it an emergency?"
"He has a sebaceous cyst that I'm pretty sure is fixing to explode.."
"oh dear, hold on one second"
So they fit us in, and when the vet initially felt the lump, he was sure it wasn't a cyst, but a mass, because a cyst is liquidy, not hard. But he poked it with a needle to check what was in there exactly and all I have to say is ew. Ew ew ew ew ew. Ew a million times. It was a cyst, but just really really really full.
Woodgie was a VERY good boy, barely noticed the guy poking FIVE needles into him to drain out all the fluid. We had the vet check out a bunch of other stuff, obviously, since we were there and Woodgie isn't exactly what you would call a late model. He has a heart murmur, and also a cyst in his eye that partially covers his pupil - this was, in fact, so interesting that the vet had to pull out a textbook to compare it to, and had another vet come in and take a look just for kicks.
Since Woodgie is about 800 years old, there isn't much we can do about all these problems. Or, rather, there aren't many things we are willing to do. Surgeries and weird medications and weird therapies, that's not us, especially not at this age. But we'll keep an eye on him for some of the symptoms the vet has mentioned to us. He's calling it a palliative approach. Knowing Woodgie he'll be fine for another 6 years.
