If you want to introduce a new puppy to an older dog, do it slowly, on neutral ground, and with both dogs on a leash. Most older dogs accept a puppy in time, but almost none love it in the first five minutes. A calm first meeting, separate spaces at home, and a quiet first week will do more than any trick.
Your older dog may be curious and gentle, and still get tired, annoyed, or jealous. Your puppy will be excited, clumsy, and rude by adult dog standards. Your job is not to make them best friends on day one. It is to keep both dogs safe and let them get used to each other at their own pace.

Before the Meeting: How to Introduce a New Puppy to an Older Dog
A good first meeting starts before the dogs ever see each other. Prepare the house first, so the older dog does not feel that everything changed at once. Give the puppy their own space — a crate or a gated room, with their own bed, water bowl, and toys. Your older dog should keep their usual bed, bowl, and resting spot.
Buy separate bowls and toys. Feed the dogs in different spots, at least for the first few weeks, so neither dog feels they have to guard their food. Your older dog’s favourite toy stays with your older dog.
Swap smells first. Let each dog sniff the other’s blanket or bed before the meeting, so the first real meeting is not the first time they have smelled each other.
Plan the meeting for a calm time of day, after both dogs have had a bathroom break and a short walk. Ask another adult to help if you can, so each dog has their own handler and leash.
The First Meeting, Step by Step
Meet on neutral ground — a quiet street, a neighbour’s garden, or a park path. Do not meet inside your house or garden first, where your older dog may guard their home.
Walk the dogs towards each other, on loose leashes, from a distance. Let them see each other, then turn and walk in the same direction, side by side, with space between them. This is called a parallel walk, and it is calmer than a face-to-face meeting. Keep it to five or ten minutes, with treats for calm behaviour.
Let them sniff, briefly, if both dogs are relaxed. Loose bodies, soft eyes, and a wagging tail are good signs. A short sniff of three to five seconds is enough, then call them away calmly. Do not let the puppy jump all over the older dog.
Watch for warning signs. A stiff body, a hard stare, raised hackles, a low growl, or a tail held high and still means the dog needs more space. Move the dogs apart calmly, without shouting or pulling hard on the leash. Try again from further away another day.
Go home together, calmly. Let the older dog go inside first, as usual, then bring the puppy into their own space. Keep the first hour at home quiet — no big play session, no visitors, and no shared toys yet.

The First Week at Home
The first week is about routine and supervision, not friendship. Keep the dogs apart when you cannot watch them, and keep meetings short.
Supervise every meeting. Do not leave the puppy and the older dog alone together, even for a few minutes, in the first week. Puppies do not read warning signs well, and an older dog can snap if they are startled or hurt. Use a baby gate or the puppy’s crate when you leave the room.
Feed them separately. Feed the puppy in their own space, behind a gate or in their crate, and feed the older dog in their usual spot. Pick up bowls after meals.
Give the older dog attention first. Greet your older dog first when you come home, feed them first, and give them their usual walk and playtime. The puppy is new and exciting, but your older dog should not feel replaced.
Let the older dog set the pace. Some older dogs want to play. Many do not. Let your older dog walk away when they have had enough, and do not force them to stay near the puppy. A safe spot where the puppy cannot follow — behind a gate, or on a raised bed — gives your older dog a break.
Keep the puppy’s energy in check. Puppies play rough. They bite ears, pull tails, and jump on sleeping dogs. Give the puppy plenty of play, training, and rest of their own.

Signs It Is Going Well
You do not need the dogs to cuddle to know it is working. Small, calm signs are enough in the first week: both dogs can relax in the same room, even if they are not close together; the older dog sniffs the puppy and walks away calmly; the puppy backs off when the older dog gives a warning, like a lip curl or a turn away; the older dog invites play with a play bow; and both dogs eat, sleep, and go to the bathroom normally.
If you see these signs, you can slowly give them more time together. Still supervise, and still give each dog their own space to rest.
Signs to Slow Down
Slow down if your older dog growls, snaps, or stiffens every time the puppy comes near, if the puppy will not leave the older dog alone, or if either dog stops eating, hides, or seems stressed all day.
Go back a step. Use the baby gate more, keep meetings shorter, and go back to parallel walks outside. Do not punish the older dog for growling. A growl is a warning, and you want your dog to warn you before they snap. Thank them by moving the puppy away calmly.
Get help if the older dog tries to bite the puppy, if either dog is injured, or if things are getting worse after two or three weeks instead of better. Talk to your vet first, to rule out pain — an older dog with sore joints or bad teeth has less patience than a healthy one. A routine exam often costs $50–$150 — prices vary by area. A qualified, force-free trainer can also help.

Frequently Asked Questions
How long does it take for an older dog to accept a puppy?
Many older dogs relax within one to two weeks, and most settle in over the first month. Some take longer, especially if they are shy, sore, or used to being the only dog.
Should I let my older dog correct the puppy?
A short, calm warning — a growl, a lip curl, a turn away — is normal dog communication. Step in before it becomes a snap or a bite.
Is it normal for my older dog to ignore the puppy?
Yes. Ignoring the puppy is often a good sign. It means your older dog is not stressed or threatened, just not interested yet.
What if my older dog is scared of the puppy?
Give your older dog space and a safe spot the puppy cannot reach. Keep meetings short and calm. If the fear does not improve, talk to your vet or a qualified trainer.
Can I leave my puppy and older dog alone together?
Not in the first week, and not until you have seen calm behaviour together many times. When you do start, leave them for a few minutes first, with separate spaces available.
To introduce a new puppy to an older dog well, keep it slow: meet on neutral ground, give each dog their own space, feed them separately, and let the older dog set the pace. Most pairs find their rhythm in the first few weeks.
