I'd rather not go all the way to brindleton just to get wellness treats, and you can't transfer funds into a rental house. The revenue is transferred directly to the household funds.
I guess it is what it is.
You could try adding the vending machine to a community lot in your own world. I don't know whether it will work on other community lots, or only on veterinary lots.
You could also try making the Wellness Ttreats yourself on Dr. Magi-Heal's Medicine Craft-o-Matic or on Dr. Budget-Bandage's Medicine Craftidink. The Wellness treat requires level 5 Veterinarian skill.
