Although Poppy is Generally Good with smaller animals, I also DON"T Reccomend a Schnoodle to be around small animals.  Any dog that is terrier or has terrier in him is not a good idea to let around small animals. and since the Schnauzer is a terrier this is not a good idea.

Years ago, I had a Schipperke that was just fantastic. They used to kill rats on the barges, yet when I bought a pet rat, she loved it. She also used to play with my house rabbit, & just to see those two playing again would be a big treat! Look up the breed and read about them. They are wonderful little dogs!!!!! 

Normally, I would try to talk you into checking out Rotties, but with the way your BF is, I'd say going with a smaller dog would be your best bet.
