Thank you for the great advice semaviLady.

I don't ever leave her alone with them. Today I had her out with me and she was eating around the ducks. After she finished the ducks took off running all of a sudden! She doesn't do this each time, but this time she took off after them (in a playful way) but I yelled 'NO, Sadie!" and she stopped right then and the ducks kept going until they got under the deck.

She's so far been pretty good with them, but she's only around 2 mon...so I know that I need to be so extremely careful and watchful at all times when she's with any of them.
She's really good with my goat. I leave her alone out in the back yard with him. He's 3 x her size and isn't the least bit afraid of her. They sleep together and seem to enjoy one anothers' company.

I have 3 cats, but one of them loves her and hangs out with her when she's outside. She doesn't ever bother him. Her favorite thing to chase is my maltese mix girl! They have a blast running around every day!
