Vinny is coming close to neuter time, he is 23 weeks today. I am hoping to have him done by the end of January. He is still only around 3.5 pounds and so small, that is what is making me nervous. What was your dogs weight when he or she was spayed/neutered? I know they s/n young in some situations as early as 8 weeks, but this is my baby we are talking about.
