Should you get two puppies at once?
We sell bonded pairs. We are also going to spend this page talking you out of one, because littermate syndrome is real and most families who take two puppies together do not know what they are signing up for.
It is a strange page for a breeder to write. Two puppies is double the sale. But we would rather place one puppy in a home that thrives than two in a home that struggles — and the second outcome is more common than the industry admits.
For most first-time or moderately experienced owners: take one. Get them settled, trained and confident, then consider a second dog six to twelve months later. You will end up with two better dogs than if you had taken both at once.
If you are experienced, have genuine time, and can commit to training them separately every day — a pair is wonderful. The difference is entirely in that commitment.
What littermate syndrome actually is
Littermate syndrome is a behavioural pattern, not a medical diagnosis, and the distinction matters.
The theory is straightforward. Two puppies raised together from the same litter bond primarily with each other rather than with you. They become each other’s security, their reference point, and their entire social world.
The consequences show up later: neither dog trains well alone, both panic when separated even briefly, and they socialise poorly with people and other dogs because they have never needed to. In severe cases the pair develop such intense co-dependence that ordinary life — a vet visit, a grooming appointment, one dog being ill — becomes genuinely difficult.
It does not only affect actual littermates. Any two puppies raised together from a similar age can develop it.
What the evidence on littermate syndrome actually says
The evidence on littermate syndrome is thinner than the confident advice around it suggests. Texas A&M’s veterinary school has a useful overview of littermate syndrome in puppy pairs if you want a second source.
Here is where we will be more honest than most pages on this subject.
Littermate syndrome is not a formal veterinary diagnosis. It is a pattern named and described by trainers and behaviourists from practical experience, not a condition established by large controlled studies. Some behaviourists argue the risk is overstated and that poor outcomes are really a failure of training time rather than something inherent to raising two puppies together.
That criticism is fair. But notice that both camps end up in the same place: two puppies need substantially more individual work than one, and households that do not provide it get worse results. Whether you call the outcome a syndrome or simply under-training, the practical advice is identical.
Treat the risk as real enough to plan around, not as a certainty. Plenty of families raise two puppies beautifully. They are, without exception, the families who did the separate work.
Littermate syndrome warning signs, and when they appear
The signs of littermate syndrome rarely show in the first fortnight. They surface later.
| Sign | Typically appears | What it looks like |
|---|---|---|
| Distress when separated | 8–16 weeks | Crying, pacing or refusing food when one is taken to another room |
| Will not train alone | 10–20 weeks | Focuses entirely on the other dog; commands that work as a pair fail individually |
| Fearfulness with strangers | 3–6 months | Hides behind the other dog rather than investigating; poor recovery from a startle |
| One becomes the “shy” one | 4–8 months | A clear confident/timid split emerges; the timid one stops coping independently |
| Poor recall | 4–10 months | Neither comes when called unless the other does |
| Same-sex tension | 8–18 months | Squabbling as they mature, most common between two females |
The pattern to watch for is not one bad day. It is a dog who cannot function without the other one present.
The real cost of two, beyond littermate syndrome
Two puppies is not twice the joy and the same effort. It is roughly twice the money and considerably more than twice the time in the first year.
| Item | One puppy | Two puppies |
|---|---|---|
| Purchase | $680 | $1,360 |
| First-year veterinary, food, grooming, equipment | $1,620–$4,260 | $3,240–$8,520 |
| Spay / neuter | $150–$600 | $300–$1,200 |
| Training time, daily | 15–20 min | 45–60 min — separately, not together |
| Separate walks | Not applicable | Most days, at least initially |
| Crates | 1 | 2 — never share |
| Lifetime cost | $17,000–$38,000 | $34,000–$76,000 |

The protocol that prevents littermate syndrome
Done properly, this routine prevents littermate syndrome in the large majority of pairs.
None of this is optional. It is what separates the families who succeed from the ones who rehome one dog at eighteen months.
Two crates, always
Separate sleeping from night one. They may be in the same room, but never the same crate. Move them gradually further apart over the first month.
Train separately, daily
Two individual sessions every day, out of sight of each other. This is the single most important thing on this list.
Walk separately
At least several times a week each. A puppy who has only ever walked beside another dog has not learned to walk with you.
One-to-one time
Each puppy gets time with each person, alone, every day. Play, handling, grooming practice, quiet company.
Separate vet visits
Take them individually. It builds independence and shows you which dog is actually coping.
Watch the split
If one is becoming the confident one and the other the shadow, increase the separate work immediately rather than waiting.
When two genuinely is the right call
Sometimes two is right, and the risk of littermate syndrome is manageable.
- You have raised puppies before and know what the work involves
- Somebody is home for most of the day
- Two adults are sharing the training rather than one person doing everything
- You have budgeted for both dogs across fifteen years, not just the purchase
- You actively want two dogs, rather than feeling sorry for the one left behind
“We did not want to split them up.” It is a kind instinct and it is worth examining. Puppies do not experience separation from littermates the way we imagine — in normal breeding every litter separates, and puppies bond readily to new people and new dogs. Taking two out of sympathy is the single most common reason families end up over-committed.
How we handle pairs
We currently have one bonded pair available, Vic and Vicky, a male and female from the same litter. They are listed together but they are not sold as a package. Either is available alone at the same price.
If you enquire about both, we will ask you the questions on this page. If your answers suggest one puppy would suit you better, we will say so — and we would rather lose the second sale than set a family up to struggle.
One note in favour of this particular pair: a male and female is the easier combination. Same-sex pairs, particularly two females, are the ones most likely to develop tension as they mature.
Questions about littermate syndrome
Is littermate syndrome real?
It is a well-described pattern rather than a formal veterinary diagnosis, and some behaviourists think the risk is overstated. What is not disputed is that two puppies raised together need considerably more individual training than one, and that households which skip that work get poorer outcomes.
Is it better to get two puppies so they keep each other company?
It helps with boredom while you are out, but it does not replace your company and it can work against training. If your main reason for a second puppy is that the first will be alone too much, the honest answer is that the schedule is the problem, not the dog count.
Should I get two of the same sex?
Male and female is generally the easiest pairing. Two females are the combination most associated with tension as they mature. Two males are usually fine if both are neutered on schedule.
What if I already have two and it is going wrong?
Increase separate crating, separate walks and individual training immediately, and speak to a qualified behaviourist early. Caught in the first year it is usually very manageable. Left until two years old it is much harder.
Can I get a second Yorkie later instead?
Yes, and for most families that is the better route. Wait until the first is confident, trained and settled — usually six to twelve months. The older dog then helps settle the younger one, which is a completely different dynamic to raising two babies at once.
Do you charge less for two?
No. Each puppy is $680 whether you take one or both. We would rather you made the decision on whether it suits your household than on a discount.
