So...I got a new chihuahuah puppy today. This thing weighs maybe 2- 3 lbs tops. Well I come home, and Donny the Rouen is in the living room. I put the new puppy on the floor and he quietly sniffs up to the duck. Donald rears his head back like a cobra, fluffs up and starts growling/hissing, then lunges forward at the puppy! I don't think he bit him, but poor little puppy starts helping and crying like he was just ran over by a truck! Donny is about 8 lbs and 3x bigger then the puppy. He is being a bully. I put Donny to bed, because th puppy needs to adjust to his surroundings, and Donald is just being.... A jerk. How have you handled new animals with your duck? I have a rabbit, and Donny hissed at first, but now they play with each other. I am hoping the puppy and Donny will be the same with time.
