Hello! We have just adopted two puppies 5 days ago from the same litter. They’re chugs, and they have brought our grand total of dogs to 5! We were only going to get one, but we ended up bringing both home (both female). I have been researching how to raise two together, and ultimately the internet thinks it’s a bad idea. So far, there haven’t been too many issues. They’re quite intelligent, they are learning basic commands quickly and toilet training is going well. They have both slept right through the night since we picked them up. I have been reading into littermate syndrome & I am quite keen to avoid this. There don’t seem to be too many issues with them being apart. Whilst they love playing together, they’re not upset if they are seperate (there is always someone with them thou) one will quite happily be in the garden with me whilst the other is in the lounge with a family member and the other dogs. However, it does become a problem with one of them (she was the runt) if she is still able to see her sister but not be with her. Tonight we tried to crate them separately (they have been in the same crate since we got them as we weren’t expecting both) and one pup laid down and went to sleep whilst the other went berserk. We ignored her, however, we became worried she was going to hurt herself because she was throwing herself at the bars of her crate and pulling on them so her teeth started to bleed. Normally I don’t advocate giving into dogs crying, however, we did make an exception tonight and placed her back with her sister, where she settled down quickly and is now fast asleep. My question is: if we work hard on training them separately, playing with them seperately, feeding them separately (we have been doing all of these with no issues so far) then is it worth separating them at night? 2 of our other dogs sleep in the same room as one another (not in crates) whilst one prefers being alone in his crate under the stairs. I don’t want this littermate syndrome to develop and would rather nip it in the bud- so will it be damaging to keep them sleeping in the same crate? If it is adviasabke to seperate We are planning to do it slowly. They will start off being fed seperately in crates next to each other, then naps in crates next to each other, then through the night next to each other, until eventually they can sleep in different rooms. Any advice would be greatly appreciated! All I get from search engines is horror stories! Thank you!
