In most homes, yes. Pugs were developed as companions rather than fighters, guard dogs, or hunters, and their default attitude to another dog is usually friendly curiosity. They rarely go looking for conflict, they read as unthreatening to most other dogs because of their small size and loose, wiggly body language, and many actively seek out canine company for play and for napping in a pile. Problems, when they come, tend to come from the other direction: a Pug's build makes him the vulnerable partner in rough games, and his enthusiasm can outlast his breathing.
How Pugs typically behave around other dogs
A well-socialised Pug greets other dogs with a wagging, circling eagerness and is quick to offer play, then equally quick to wander off for a rest. Pugs seldom guard toys or space with real intensity, which helps them fit into an existing group without challenging an older resident. Same-sex friction and status disputes are uncommon compared with many breeds, though no breed is exempt from individual personality. A Pug who has had little contact with other dogs as a puppy may be nervous or overexcited rather than aggressive, and that is a socialisation gap to close gradually, not a character verdict.
Size differences are the main thing to manage
Pairing a Pug with a much larger, boisterous young dog is the combination that needs thought. A Pug's prominent eyes can be caught by a flying paw, and a heavy dog landing on him during chase games can injure a back or a leg. Supervise early play, interrupt games that get frantic, and give the Pug a genuine choice to leave, because he will often keep playing past the point his breathing can support. Watch for hard panting, a wide, raspy struggle for air, or a blue tinge to the tongue during play with a bigger dog; those are stop-now signs, and repeated episodes are worth discussing with a vet. Two Pugs, or a Pug with another small, steady dog, is usually the easiest pairing of all.
Setting up introductions that go well
Meet on neutral ground first, on loose leads, and let both dogs sniff, circle, and move away freely before anyone is off lead together. At home, feed separately for the first weeks, keep high-value chews out of shared spaces, and give the newcomer his own bed and water bowl so nothing needs defending. Short, successful sessions build the relationship faster than one long, tiring first day, and ending play while everyone is still relaxed teaches both dogs that the arrangement is safe. Most Pugs and resident dogs settle into an easy companionship within a few weeks when the early meetings are kept this unhurried.
When another dog joins through adoption
If your Pug, or the dog he will live with, arrives through adoption or rehoming, the receiving household is guessing unless the history travels too: how he has lived with dogs before, what play style suits him, what frightens him. Ask for that detail explicitly rather than discovering it at the first meeting. KinsLe's Transferrable Profiles are built for exactly this handover, carrying a Pug's social history, health records, and daily routine to his new owner intact, so introductions with your resident dog can be planned around the Pug he actually is, not a hopeful guess.
