we have 2 dogs, both short haired but they malt a rediculous amount, and they are trained to stay at the door if im not in Summahs room, if im in there they are allowed in, and in all honestly they come in for 2 seconds sniff around and leave again, there isnt really a great intrest in being in there really.

occasionally if she cries they will go in and see her and come straight out, which im ok with.

i vacum every 2-3 days depending on how much time i have, and im fighting a loosing battle, with 2 malting dogs there is no way ill ever keep the fur out of her room, or away from her in general.

find some rules your happy with, ie dogs sitting at the door and not going in there, and start implementing them now.

i agree with Nae and Krystals, its important to set up things like bouncers and what not early so the dogs get used to them being there and what not.
my DH bought home blankets and clothes when DD was still in hospital and put some in her cot, swing, pram and bouncer so they got used to her smell being on the things we had scattered around the house, now they have little or no intrest in her.
they will sit next to her on the floor if she is laying on her mat, our boxer will sit outside her room occasionally but they really dont bother with her to much... YET!
