Litter mate syndrome?

Has anyone ever who has bought two puppies together from anybody in the past had issues with what they call litter mate syndrome? Another words they can develop severe behavioural issues and aggression if they are brought up together? Any urgent help would be useful as I have a family Buying two of my puppies Who are really worried at the moment about the puppies having issues if They are brought up together.
Rebecca Crane I have a direct brother and sister and they are completely fine. 2 years old now and totally normal dogs with my other adults.

Michelle Andrews I have never heard of this, everyone I have ever know that has had 2 from the same litter have been just fine. Only issue is if maybe you get 2 alfa females.

Ellise Louise I wouldn't do it with the runt and another. Runt could get bullied. Otherwise sounds great!

Sarah Anderson I have almost 4 year old litter mates, a male & female. I will tell you, I was warned. We worked very hard to give them separate interests & work them separately. They love each other and are bonded with us. It can be difficult. I would imagine it depends on breed & owner/situation.

Shawna Lopez I’ve always gotten puppies in pairs. It is important that they spend individual time with them, both in obedience training and play, and treat them independently. Separate crates (but they can be side by side for comfort). Also make sure they follow through with spay/neuter at appropriate time.

The key is to not make the pups dependent on each other 24/7.

Melanie Locke Not problematic if pups are socialize, trained and seperated occasionally. Any two animals (litter mates or not) can have those same issues. I would make sure if you sell littermates they are compatible in personality...just as someone else mentioned not a dominate puppy and a weaker runt etc.

Lyric Anderson I wouldnt really be worried about aggression just the annoyance of separation anxiety. Ive always had pairs and i feel it actually eases the transition and gives them a little comfort. As long as they aren't aggressive prior to selling i think they will be fine. Its up to the owners to train accordingly

Angela Wilson I'm going to tell u right now that if u sell those siblings together and they have that issues, which is very likely, they are going to trash your reputation because everyone will comment about how a good breeder wknt sell siblings together.

Liz Dimbleby Crate train separately. Spend individual training time with each dog as often as possible. Have pups off independently frequently so they get used to not being together and so not totally dependent on each other. Our 3 are outside dogs for a number of reasons and this has worked really well.

Tom L Beatty Jr. What breeds? I have hounds and have kept 4 from first litter 2 from 2nd and one from 3rd... got puppies now and am planing to keep 2. I have not noticed any problems and they hunt real well together, like hounds should in a pack and honoring each other when they find a track. They play together when at home and eat next to each other without issue.
