Apparently it can die, and I don't want that to happen.
Can I make it stay at my house? It's so cute!

I have the cute little spider..
It occupies the same follower role as the dogs, so maybe you can persuade it to stay at your house. I've never tried that. Talk to it, if you can, when you're at home.
I like the Dwarven Sphere the most. Only thing is it doesn't seem to do much damage
I always liked the dwarven spider. It's as basic as followers can get though, and can't interact with much in "people world". Still, I like to have it follow along for a dungeon or two whenever I'm in Solstheim, but always take him back home when we're done.
The machines can produce a new one if your old one is destroyed. For free!
Cute little feller makes me want to go to the island for the first time. RIP little guy
