I cannot see floating anything less than a 1/2" engineered, unless it's a laminate. And speaking of laminates, since you will only be there a short time, that would be a consideration for your large, slobbery pooch. One always risks when one cuts corners, like buying an unknown brand that may not handle a claim well. My preference is ALWAYS to buy from a distributor that will assist me in any claim I may have against a product. As the knight in "Indiana Jones and the Last Crusade" said: " Choose wisely."
If you don't and you "choose........poorly" , this is how you'll feel after.
