Welcome! You are sooo in the right place to learn!
Thank you for considering adopting this pup, and for adopting kitties! There are tons of training helpfuls in the Training section to help you out. Please consider the "2 weeks, give em a break!" thread, as well as the "introducing a new dog" thread. Did the rescue say they've tested him with cats? I would make sure they have, if you haven't already. Just like bringing in any new pet, it will take a couple of weeks to get in a routine and for them to get familiar with each other. Please be patient, and keep the intros short and positive until they are ok together. Also, never ever leave the dog and cats unattended together...this goes for any breed of dog. Better safe than sorry.
