Here’s my situation, Winnie is almost a year old and spayed. This morning I brought home an 8 wk old male flemmish giant(not nuetered yet). When i brought home the baby, i didnt take it in winnies room, but i did let Winnie smell be a bunch of times for at least 2 hrs, while flemmie stayed in the living room with me. When sniffing me, she would get crazy and start running around me a bunch. 

She is obviously territorial right now(that is her room lol) but she wants to attack the male baby..like bad!! Im saddened:/ 

So, the flemmish baby is in a cage in winnies room.(winnie is free range in the room). I had to put high pieces of card board around the cage(so Winnie cant see the baby, she can only smell him). I had to reinforce the cardboard cause Winnie was trying to tear down the cardboard to fight.  Winnie wants to fight him, but she is also doing binkys around the room? she is currently sitting in front of the cage gaurding it.

Is this what i should do for a couple weeks? until Winnie is no longer territorial? Will Winnie come around? Any advice please??

The flemmish is the sweetest little guy and is not trying to fight Winnie. Winnie wants him dead right now.
