"These puppies"... housebreaking more than one at once is gonna be a challenge!?! First dog that was ever all mine... 8-10 week old Dobie. We were in an apartment... NO PETS... for about a month before moving into a house. It was August, and being a teacher... no school. This was WAY before crates became popular. I NEVER left the puppy alone... didn't want her to be heard crying... which was very likely, even if shut in tiled bathroom. I pretty much slept in clothes, with flip flops right at side of bed ready to slip into. The MINUTE she woke up... scooped her up, grabbed leash and head outside... via BACK DOOR!?! Walked around until she did #1 and #2. As soon as she finished eating... repeated routine. Same with when she was sleeping during the day or playing. Did this for probably 3-4 weeks, outta necessity. By the time we moved... house had fenced yard... she was pretty much house trained.

Don't know about multiple puppies. If you have fenced yard... I'd probably shoo them out as often as possible.

There is a search feature at the top of this forum and then are several threads with lots of great potty training advice.
