To Snip Or Not To Snip

There is so much conflicting information out there on when to spay or neuter your pup.  The vets, these days, are telling pup parents to wait 14,16,24 months before spaying or neutering.  They report the pups reach their full height and it will decrease likelihood of injuries later.  However, people have historically altered their pups as early as 8 weeks.  What is a pet parent supposed to do? I have my take, as a trainer and daycare owner, in this podcast.
