Don't worry about it being built on a landfill. The EPA and whatever state agency you have that governs environmental concerns have to test it and approve it for humans before it will be allowed to open. Plus they have to bury that stuff under at least 3 feet of soil, I think most places go 4-5 feet to be safe.
Like several others said, get your dog fully vaccinated first. As for one particular vaccine, make sure you have kennel cough vaccine, while you won't be putting your dog in a kennel thats just a nickname for it, it's contagious just by walking past another dog with it. And make sure you get it re-upped every 6 months, thats how long it lasts.
