Help! Poddy Training my Goldendoodle

Hello to anyone who might have some answers for me that I'm not coming up with.
I know my puppy is smart, but I can't seem to get him to stop peeing AND now poophing on our floors. Luckily we have alot of tile in our home.
I am doing the crate training (we have an 8 yr. old Standard Poodle) and it's not working. I'm wondering if maybe his blader is too small - if maybe he doesn't get the sensation of having to go until it's upon him. I love him enormusley but I'm going back to work now after the summer off and I'd like him hurry this deal up! Bought him in July so I could get him house broken before going back to work. I go back in two days.
