Thanks for the advice, everyone. It looks like Toby's going to pee like a girl forever....
we definitely do not want him to begin marking our house so he'll be going under in the next little while.
When I mentioned it to my vet, he seemed pretty adamant about waiting until 1 year, I'm not sure if he will do it. I will ask him again next week, and if he refuses I may be asking for some advice as to where to go.
Just out of curiosity, it's interesting that each of the replies I recieved were for the 4 month fix. Does anyone know why some people like to wait until 1 year? My vet didn't really elaborate and we were there for something else so I wasn't really focused on it. But now that i am thinking about it...I am curious!
Have a fabulous holiday weekend everyone! We are going camping in New York State, so I'll check in on Sunday when we return. Toby's first camping trip - we are very excited!
