Thanks for all the great advice.

Charlie was about 2 1/2 when we adopted him in December 2005, so he was about 2 when he was neutered in July 2005. His teeth were in great condition.

Like I said, the vet actually did surgery on him last summer (June 23rd, to be exact) to try and find his missing testicle. She kept him under for 2 hours and did not find it. Said it wasn't there... and that it could have been like the other case where she had seen that it had sort of disintegrated.

Before they did the surgery on him they did tests on some of his organs... like his kidneys and his liver I think. They were alright in June 2006.

The vet appointment is at 9:30 in the morning, so I'll post an update when I return...

Thanks again!
