I agree with captjack. I have not neutered our 2 year old dachshund.

1. Dachshunds have bad reactions to anesthesia as a breed in general.
2. I have never had any issues with him marking in the house or with any aggression.
3. I am of the opinion that we do not do needless surgeries on humans why do them on our pets. My husband and I are responsible pet owners and he isn't roaming the streets. I have a very close friend who lost her puppy during this surgery.
