How to introduce a puppy to an older dog

An older dog did not ask for a puppy. It is being handed a small, sharp-toothed housemate that wants to climb on it, chew its ears and play at 6 AM, often at an age when its joints ache and its patience runs shorter. The introduction goes well when the older dog's comfort comes first and the puppy's enthusiasm is the thing being managed.

Before you start

Before you start, check the older dog's health and build it a puppy-free space

Start with the vet. The AKC's guide to introducing puppies to senior dogs warns that a puppy can be a threat to an older dog with heart, back or spine problems, and that a senior dealing with pain, arthritis, incontinence or hearing loss may not be a good fit for a new puppy. A check before the puppy arrives tells you what your older dog can manage. Have the puppy examined too, and make sure both dogs are tested for parasites, the AKC adds.

Then build the geography. The older dog needs a room or a gated corner the puppy cannot enter, with its bed, water and a soft place to lie, ideally where it already likes to rest. Put away toys, chews and beds the older dog values before the puppy comes home, and set out more than one water bowl, which the AKC suggests to cut down on guarding. A senior that knows it can always retreat is far more tolerant when it chooses to stay.

  • A vet check for pain, heart and mobility first
  • A gated, puppy-free rest area for the older dog
  • Prized toys, chews and beds put away
  • Two water bowls in different spots

The steps

Neutral ground, then minutes at a time: seven steps through the first weeks

The first meeting belongs on neutral ground. The AKC's advice is to meet somewhere neutral, walk the dogs side by side with one handler each, and let them get to know each other in a low-pressure way. For a puppy that has not finished its vaccines, your vet decides what counts as safe ground; a friend's quiet yard or the edge of your own street may be the answer, rather than a park other dogs use.

After that, time together is rationed. The AKC suggests that when one dog is much more playful, you move it away every minute or two, give the less playful dog a rest, and let that dog decide whether to start again. With a puppy and a senior, the puppy is always the more playful one. Short sessions that end calmly build the older dog's tolerance; one long afternoon of being climbed on uses it up.

  1. 01

    Walk the dogs side by side on neutral ground, one handler each, for several minutes before any sniffing.

  2. 02

    Let them sniff briefly with loose leashes, walk on, and repeat once or twice.

  3. 03

    At home, let the puppy explore while the older dog rests behind its gate, then swap.

  4. 04

    Bring them together for two or three minutes, puppy on a light leash, and lead the puppy away every minute or so.

  5. 05

    End each session while the older dog is still relaxed, and give it time alone afterward.

  6. 06

    Feed them in separate rooms, and greet, leash and feed the older dog first.

  7. 07

    Lengthen time together only as the older dog starts seeking out the puppy instead of moving away.

Separate rest

Give the older dog separate rest every day, and read what it is telling you

Rest is the part most households skip. A puppy needs most of the day asleep and an older dog needs quiet too, so rotate them: the AKC recommends a gate or crate to separate the dogs and rotating them through the day, so one rests while the other explores. Keep the older dog's walks, games and one-on-one time with you, and do not make it bring the puppy every time it goes out.

Then watch the older dog. The AKC describes subtle stress as turning away or moving off when the puppy approaches, and obvious trouble as growling, snapping and lunging. Some older dogs correct a rude puppy at the right time and intensity, which is useful teaching, but the AKC is clear that you should step in when a puppy repeatedly harasses an older dog rather than leaving them to work it out.

  • Turning away or leaving the room: give the older dog a break
  • A brief growl that stops the puppy: fine, then separate them
  • A puppy that ignores a warning: lead it away
  • Snapping, lunging, or a senior that stops eating or sleeping well: call us

Mistakes we see

The mistakes we see are the puppy license myth, the shared bed and the senior left to cope

The so-called puppy license, the idea that adult dogs will tolerate anything from a puppy, is the first. Some older dogs are patient; many are not, and a sore, tired senior has less patience than most. Leaving the dogs to sort it out is the second. A puppy that keeps climbing on an older dog after a warning is learning to ignore warnings, and the older dog is learning that it has to escalate to be heard.

The shared bed and the shared bowl are the third. An older dog asked to give up its bed, its toys or its spot by the radiator to a newcomer has every reason to guard them. The fourth is taking the puppy everywhere the older dog goes, until the senior's slow off-season stroll on the flat sand at Good Harbor, allowed on even-numbered days through March 31 at the time of writing, becomes a puppy-minding job. Keep some outings for the older dog alone.

  • Trusting a puppy license that may not exist
  • Leaving them to work it out
  • Shared beds, bowls and favorite toys
  • No outings for the older dog alone

When to call us

Call us if the older dog snaps, hides or stops enjoying home, or if the puppy will not take no for an answer

An older dog that snaps, hides, eats poorly or seems unhappy at home needs a plan before the puppy gets bigger, and a vet visit too, since pain often sits behind a short temper. VCA recommends a vet exam at least twice a year for seniors anyway. The AKC suggests working with a trainer or behaviorist if you are unsure how the dogs are getting along. Adventure Academy includes controlled introductions and structured socialization, and private sessions with Gabriella Pope, our Director of Training & Canine Behaviorist, start from $94.

For the puppy, Tiny Tails Puppy School from 8 to 16 weeks covers life skills and the settle, and AKC S.T.A.R. Puppy runs to 6 months. Daycare can give each dog a break from the other. A senior that still enjoys company can spend a $33 half day in a calm group, and a vaccinated, licensed puppy can do the same in a group matched to its size, each after its own free evaluation on a weekday between 6:30 and 9:30 AM at 210 Eastern Ave.

Asked and answered

Questions people ask about this

Short, complete answers you can act on today. More in the full FAQ.

Is my dog too old for a puppy?
Sometimes. The AKC notes that a senior dealing with pain, arthritis, incontinence or hearing loss may not be a good fit for a new puppy, and that a puppy can be a real risk to a dog with heart, back or spine problems. Ask your vet first. A sociable, healthy older dog with a quiet place to retreat often does well.
Should I let my older dog correct the puppy?
A brief growl or air snap that stops the puppy, followed by both dogs relaxing, is normal dog communication, and the AKC notes that some dogs correct a puppy at the right time and intensity. Do not punish the growl. Step in when the puppy keeps pushing after a warning, or when the older dog's warnings get harder or more frequent.
How long until my older dog accepts the puppy?
Anything from a few days to a few months. Judge by the older dog, not the calendar: when it starts approaching the puppy, lying near it by choice and playing in short bursts, you can lengthen their time together. Until then, keep sessions short and supervised, followed by rest apart, and never leave them alone together.
Can the puppy and the older dog sleep together?
Not at first. Give each its own bed, and give the older dog a sleeping spot the puppy cannot reach, so it never has to share or defend its rest. Many pairs later choose to nap together, and that is fine once the older dog is the one choosing it. Crate the puppy at night for its own sake as well.
Can both dogs come to Dogtown?
Yes, as long as each passes its own free evaluation and has a current city license, and the puppy has finished its vaccines. They may not share a playgroup: groups of 7 to 10 dogs are matched by size and temperament, so a senior and a puppy may be placed in different groups, which we decide at the evaluation.
