Wow, I was going to ask if you lived in California! They charge out the wahzoo over there for vet services in some parts. I guess NYC shouldn't be a surprise for high costs either. I believe ours averages aroung $300 including pre anasthesia blood testing. It sounds like your doggie doesn't have *much* of a marking problem so maybe it will go away. Usually once a dog starts marking tho it doesn't stop after neutering. I have had dogs that were neutered before they started marking to start marking later in life depending on their personalities, and others who never were neutered who never marked. So hope for the best!
