Imagine getting two cute, adorable puppies from the same litter and bringing them home to be a part of your family.
You might think you’re doing a fantastic thing, keeping brother and sister pup together. Cuddling will be double the fun!
I actually sort of considered getting two Rottweiler puppies but am supremely satisfied with just my female Rottweiler Amalia. Another couple actually got a male and a female, but dangers lurk behind doing this.
However, there’s a potential monkey wrench in your best-laid plans. If you choose two sibling puppies, then you could face challenges due to littermate syndrome.
Littermate syndrome describes the phenomenon when two puppies from the same litter grow up together in the same home. The puppies get so attached to each other and form such a deep bond, it can spark behavioral issues.
Unfortunately, it can also prevent your puppies from bonding with you, leaving you feeling a little bummed to say the least.
Is Littermate Syndrome Real?
While not an exacting scientific or medical diagnosis, the concept of littermate syndrome is very real.
However, that doesn’t mean it’s necessarily a given situation for all sibling pups that you raise together. As with many things, multiple factors can influence the probability and severity of littermate syndrome.
But, there has been quite a bit of evidence suggesting it best to avoid sibling dogs. In fact, in some cases, even unrelated puppies adopted at the same time can exhibit signs of littermate syndrome.
Therefore, if you want more than one puppy, you risk dealing with several behavioral problems.
The theory is that you adopt puppies during a critical time in their development, around 8 weeks. This time is the age when puppies can start to leave their mother. During this crucial time, littermates possess a deep bond to each other, recognizing each other by scent.
When puppies share this strong bond, it discourages them from interacting with their human family. This lack of interest or interaction inhibits their ability to start understanding canine-human communication.
It can also influence how your dogs react and interact with other dogs.
A lack of socialization caused by disinterest in the environment and perhaps other dogs can potentially lead to behavioral issues as well.
What Age Does Littermate Syndrome Start?
Typically, puppies stay together with their mother until at least 8 weeks. Between 8 and 12 weeks is when most breeders deem it okay for pups to leave the nest.
If you adopt two puppies around this time and raise them together, you could see signs of littermate syndrome as early as 8 to 10 weeks if puppies stay together after leaving their mothers.
However, slightly older puppies still less than 6 months of age that are raised together can also experience littermate syndrome. So, basically, issues can begin as soon as young pups leave their mom but stay with each other, whether it’s 8 weeks or 6 months.
What Are the Symptoms of Littermate Syndrome?
If you’ve adopted two puppies from the same litter, you might start noticing some concerning behaviors. For example, your pups might whine or bark frequently, seem overly fearful or anxious in new situations, and be challenging to train.
You might also notice your new furry family members paying little to no attention to you.
All these can also be caused by a variety of other (non-concerning) factors or a lack of a proper training program.
Be on the alert for clues the dogs might show through their interactions (or lack thereof) with humans. Also, take particular note of how the two dogs behave when they are apart and when other dogs are around.
Here are a few possible symptoms of littermate syndrome:
- The dogs show fear or anxiety toward new people, experiences, and other dogs.
- Puppies display extreme separation anxiety when they’re away from each other. Potential signs can be excessive barking, whining, pacing, and destructive behavior.
- The dogs only eat when they are together.
- You might notice a lack of focus and difficulty with things like training because the dogs distract each other constantly.
- The puppies only seem to want to play with you if they are together.
- The dogs might fight with each other or show aggression towards other dogs.
Always take a holistic approach and evaluate all the criteria one after one and check if they could be caused by something totally different.
How Common Is Littermate Syndrome?
Although littermate syndrome is not a guarantee, it’s a fairly common occurrence when you adopt puppies the same age.
In addition, some believe that certain breeds are more prone to littermate syndrome than others. However, there are no evidence-based studies to back up these claims.
Overall, professionals recommend avoiding adopting puppies younger than 6 months old at the same time. However, it’s best to be prepared to put certain steps into practice if you insist on doing so.
You’ll need to stay dedicated and consistent if you want to try and avoid littermate syndrome.
Does Littermate Syndrome Always Happen?
In a nutshell, no, littermate syndrome doesn’t always happen. However, a lot depends on environmental factors and how you raise the puppies.
If you don’t make a point to treat them individually, then the likelihood of littermate syndrome increases significantly. A lot also depends on how soon you start working toward preventing littermate syndrome.
How to Prevent Littermate Syndrome?
Of course, the best way to try and prevent littermate syndrome altogether is to adopt dogs of different ages. For example, you could adopt a puppy but then select an older dog for your second pup.
Another option that could also be successful is to adopt your dogs at least six months apart.
When you stagger your timeline for bringing home your new pups, your dogs are more apt to bond with you. Plus, it’s a lot easier for you to focus on helping one dog get acclimated at a time to their new environment. This idea is a good practice no matter your dogs’ ages.
However, whether you choose one of these options or move forward with adopting littermates, it’s essential to socialize your puppies properly. It’s also vital to start your action plan right away; the longer you delay, the more likely littermate syndrome will develop.
Furthermore, it’s critical to treat your dogs as individuals, making a point to spend time with them separately. Not only does this one-on-one time help ease the effects of littermate syndrome, but it also helps you bond with your dog.
Can Littermate Syndrome Be Cured?
If your dogs are already exhibiting signs of littermate syndrome, all is not for naught. It will take a lot of dedication, but yes, it is possible to remedy the situation. However, immediate action is best.
The sooner you can start working on a plan to resolve the various issues, the better. Separating your dogs for training is a significant part of this plan so that you can work with them individually.
Remember, it’s about each dog feeling comfortable and confident in their own skin and with their human family.
However, if your pups already share a strong bond, you may need to ease into the separation gradually. Again, if you plan to adopt two puppies simultaneously, it’s best to prevent littermate syndrome from occurring in the first place.
Employing the following techniques can potentially help ease existing signs of littermate syndrome.
- Crate your dogs separately, leaving the crates side-by-side at first and then gradually moving them apart. Eventually, the ideal situation would be to have the crates in entirely different rooms.
- Train your dogs separately as well. Plan out a training schedule where you only work with one pup at a time. If you plan to enroll in obedience classes, do two separate classes on occasion.
- Work on socializing each dog independently; take your dog to public settings, go on a walk, and enjoy some play sessions. Then, repeat the same activities with your other pup.
- As your dogs start to become more independent, you can gradually ease them into joint activities. Enlist the help of another family member or friend. For example, if you plan to take both dogs on a walk, you handle one and your friend the other.
- Even as you start to have joint training and play sessions, still maintain individual sessions with each dog as well.
Do Dogs Outgrow Littermate Syndrome?
Without a thoughtful and constructive action plan to remedy behavioral issues, it’s improbable your dogs will simply outgrow littermate syndrome.
If you want to be able to get the situation under control, it’ll be because you’ve allowed them to develop independently and receive proper socialization, not because they’ve outgrown anything.
Besides, training one puppy is hard enough – trust me, I know. Puppy blues times two incoming.
As with anything when it comes to your pets, if you’re concerned about their well-being, talk with your vet.
