I had my Maltese Codie neutered at 8 months of age. I wanted to have him done when he was 6 months old but my mother got VERY sick around that time and I had to take a leave of absence from work and take care of her. So unfortunately Codie's surgery got post-poned for a while. Codie does hump things and I believe it was because I waited until he was 8 months old. He humps his favorite stuffed animal which is a GIANT Pug. He has also occassionally humped my mother's (his grandmother) leg - it's hysterical!!
