He's a big boy so I'd have no way to still play of he was on my lap.

A good 25 or 30 years ago, I was making an EP of guitar instrumentals intended to pay homage to famous guitarists.
On one song called "Saturated" I opened with a feedback note, did a tapping intro and ended on a different feedback note.
Each feedback note, our dog Barney would howl. And he hit different pitches on those 2 different notes. He wasn't in tune, but he was consistent. Because it happened every time, I decided to have him in the room while I was recording it.
Anyway, when I finished it and made liner notes for the cassettes, I had all instruments by me, drums by Dr. Rhythm (my drum machine at the time)-and vocals by Barney. It was an instrumental album but Barney got vocal credit!

Where do I find this EP?

Something I am going to do when I retire...

Gonna buy one of those mini-houses, put it next to my current house (So the wife has her space too) and kit it out with all my guitars and build a half-ass recording studio...then do exactly what you did...see if I can make an entire record.

Although, the technology of the day is a little intimidating...not even sure where to begin.

Cheers.

Just did it for my own entertainment.
I recorded these songs post retirement. So, your plan us similar to mine.
