With a male, I would want to neuter before marking becomes an established habit, so closer to 8 months maybe, although it depends on the dog. My vet also considered if enough of the adult teeth were in because Yorkies don't lose all their baby teeth on their own, most Yorkies have at least a few that will need to be pulled and this has to be done under anesthesia, so it's best to have it done when neutering. A double row of teeth can cause future dental problems.
For me, one of the main reasons you neuter a male is that the number one cause of death for unneutered males is death due to injuries from car accidents, your unneutered male is much more likely to bolt out the door every time you open it, he can smell a female in heat up to 10 miles a way. Also, remember that males and females are fertile all their lives, and so you always have to be extremely conscientious if you have a unneutered animal. |
