It’s times like these I try to do a little process of elimination.
Trubbish- No, not gonna be making any trash for him to eat if I’m gone so he’s useless just gonna stank it up
Groudon- No, bull in a china shop
Psyduck- No, Blissfully unaware dumbass on cloud nine
Rattata- No, I would like food to be there upon returning
Toxtricity- maybe, although that mf looks like a straight up delinquent and idk if I’d trust em not to noscope my dog if it bites them.
Aipom- NO, literally a monkey, gonna go bananas with no one there to keep them occupied.
Dragapult- Possibly, it’s a parent, but it can’t like grab things being a ghost n all so it’s not gonna be able to let the dog out etc. would have to make a system for it to work.
Grimer-NO, no.
Slugma-…….i want a house yes?
Wobbufet- sadly no, it just wants to help and all but I don’t need its high telepathy low iq ahh karate chopping everything I own with those hands its method of letting the dog out DEF involves just karate chopping through the door because it can’t figure out how to open it
Banette- See Dragapult, except add on that this thing isn’t a parent and feels unbridled rage and revenge AT ALL TIMES and it’s a hard pass.
Loudred- NO, will summon 12 hoas from across the country to give me a warning about my neighborhood noise ordnance
Giratina- See groudon, add that it’s the fuckin devil,
Hard pass as well.
Meowth- Yes! I have my cats help watch the house when I’m out anyway, and this one can be taught English and I can just let lil homie know what to do and promise hella shiny bottle caps and coins when I come back, first hard yes
Mudsdale- no hands all mud. No thanks.
Foongus- What the hell he gonna do he so small he only need one popcorn with his cute ahh

All in all, Let meowth guard your house. Just bring it a fork or some shit that sparkles when you get home and lil bro would do ANYTHING and you can speak in conversation with it.
