Same here. IMO, that's the best all round solution.

I have two boy littermates and they are fine together, yes it has been hard work etc etc and they do get walked separately at times. Both are very well socialised and nothing seems to phase them. One is boss and the other one is more of a couch potato but they adore each other and have slept in the same bed since they were 8 months old (they do have a bed each!) However, a friend of mine has two females who have fought so much with each other that she recently paid for a police dog trainer to help her with them. It all seems to be calm at the moment but who knows for how long.

Incidentally I've had lots of experience with dogs and only agreed to take on two from the same litter a week before I was due to collect one. The 'other one' was diagnosed with a heart murmur and could not go to the show home it was due to go to so I was asked to take him on (at no cost). He is gorgeous and 'the boss' and is always on the move.

my mum has 2 male westies from the same litter and they get on just fine have odd scraps but no more than ive seen others dogs do. But my dad has 4 yorkies the mum, 2 from 1 litter ( boy and girl) then 1 from another litter a girl. the 2 girls are at it all the time and has ended up in a few vet trips. This has only just started though one is 7 and the other is 5.

its a very tricky one but not sure i could cope with two puppies

My friend did it, acquired litter sisters, this was before I knew her. She go two Mini Schnauzers together and maybe because I got to know her and I would take the two puppies to my house with my own Mini, that they have grown up the way they have. I dread to think if they had of been on their own when they were puppies with no human intervention, regarding house training etc., I sometimes wonder how they would have turned out, but they are now a year old, and apart from one being quiet and the other not so, they have turned out quite well, with a bit of guidance from my fella, who because he is such a little darling with lots of patience he has shown them the error of their ways.
The only thing I would say here, it is alright to have litter puppies if you aren't in full time employment, and have the time to train two together, and bearing in mind some breeds are better than others, and also the breeding and temperament of the line you are buying from, and whether the breeder has socialised them all these factors matter a great deal. Most importantly how much experience one has is of prime importance too. It is not for the faint hearted. Some breeders would not think it important to ask if the prospective buyer is experienced or not, which they should do as most of you have said.

Both and especially if they are the only two dogs in the household. Most reputable breeder would never sell littermates, let alone two sisters, to the same owner. I've had a mother and daughter and that was bad enough, but two sisters is just asking for trouble and the bigger the breed, the bigger the problem. My friend got two westie litter sisters and they were chalk and cheese. Well, more like Jekyll and Hyde. One was lovely and the other was such a psycho that when she went missing at the age of about 3, nobody bothered to go looking for her. The psycho one was the dominant one and also much less responsive to human interaction and direction. Once she was gone her sister blossomed as an only dog. My mum's friend got two jack russell litter sisters and they were constantly at the vets getting them stitched up after fights.

Actually, I can't think of anybody I know who has done it and has a positive story to tell.

all the dogs are meant to stay down stairs,but tarn sometimes gets to sneak into my sons room(tarn gets spooked easy (he heard a mouse under the floor and went into a panic couldnt calm him down)so now when ever he hears a sqeak!! he is of up the stairs. Puppies are in the bedroom at night but through the day they have a grate set up in the kitchen,has worked ok for mine.Years ago i had 3 gsd and they all slept up stairs in my sons room,but found out he was letting the dogs have his bed and he slept on the floor so that was why we stopped them
