Good to hear that everything is normal. It sounds like your vet is happy with just doing bloods, so he is probably just fine.
I tend to be very cautious because it is easy to miss things. So doing more testing is something I'd strongly consider if this were Ellie (and if anything remotely similar happens again - that would turn into immediate testing).
What heartwork preventative is he on?
When was the last fecal done?
Did your vet mention anything about a comprehensive fecal?
Some bacterial and parasitic infections can be hidden. Hot Rod is likely at higher risk because of his diet. Sometimes these things can cause a dog to go hypoglycemic. That would be my major concern right now.
Kibble, anal gland issues, and upset tummies should not cause hypoglycemia. When shaking stops and/or grayish gums come back to normal color after giving sugar to an adult, that just isn't promising to me. JMO
