Welcome to YT and congrats on Tucker! We had Huey fixed at 6 months, 1 day. I don't remember him having any big issues after the surgery, but since I am home during the day & dh at night, there was someone with him. I personally like to be around at least the 1st 24 hours after any type of surgical procedure. I surely wouldn't leave him more than a couple of hours at a time for the first day or two. That's just me...others will probably have more/better advice based on experience than me and my gut feeling.
Again, welcome & good luck with the Neutering.
