WOW Chrisanne he is a big boy, and sure sounds quite healthy

I would do the microchip when you get his rabies done, that is JMO because it really isn't that bad, we only had 1 of our dog's and ONLY 1 of the cats not care for the injection. The other's didn't seem to care at all. I know the needle seems HUGE compared to a regular vaccination needle, but I'm sure he'll be just fine

But if you want to wait until he is to get neutered than that will work too

Can't wait to see updated pics (hint, hint)!!
