Raiko, it is better to raise any two dogs seperately even from the same litter. Get one then a year and a half or two get the second. Train and socialize A LOT with humans and other animals especially the first year. I've even seen poodles with "kill" instincts (a black female year old bitch from a litter a local breeder bred and raised killed a smaller dog in the family) so definately look at the temperment of the parents. Even with my two boys they are always supervised. Sam was fixed at 5 months (he is an Alpha male and moody - 68 pds) and Buoy (10 pds) is intact and is proud. He thinks ALL the girls are his.
