Toulouse geese generally cope well with other pets, largely because of their size and self-possession. A full-grown Toulouse is one of the heaviest domestic geese, and animals that might bother hens often decide a bird this substantial is not worth the argument. The geese, for their part, are not looking for conflict: they want their grazing, their water, and their own corner respected, and they are content to ignore most neighbours who grant all three.
Dogs: respect usually runs both ways
A calm dog and Toulouse geese typically reach an armed truce that matures into indifference. The geese may hiss a warning when a dog first comes near, and a sensible dog backs off and files geese under animals to walk around. The danger cases are dogs that chase for sport and dogs that grab: a goose cannot fly away from trouble, since Toulouse are too heavy for more than a short flutter, so a determined dog in an enclosed yard can do real harm before anyone intervenes. There is also the opposite script, where a breeding-season gander stands his ground and rushes the dog, and a surprised dog retaliates. Shared space should stay supervised, with the dog's early sessions on a lead, until the truce is proven boring.
Smaller poultry need protection from the geese
Toulouse geese often bully the birds below them in the yard hierarchy. Ducks and hens sharing feeders with geese get shouldered aside, and a goose's bill can injure a small bird in a squabble over scattered feed or the best bathing spot. Mixed flocks work when the design removes the contests: separate feeding stations, water the ducks can reach away from the geese's pool, and night housing that gives each species its own sleeping area. Goslings, ducklings, and young pullets should never be loose with adult geese that are not their parents, because the size difference alone makes accidents likely even without any malice from the big birds.
Cats and other small neighbours
Cats rarely register as either threat or interest to adult Toulouse geese. A cat may watch the flock from a fence post, and the geese may comment, but a bird outweighing most cats several times over is not prey in any practical sense. The exception is again the very young: goslings in their first weeks are cat-sized and fragile, and they belong in a covered pen until they are sturdy. Outdoor small pets like rabbits should keep their own runs rather than sharing goose ground, since a rabbit underfoot during a flock's rush to the gate is at risk from plain trampling.
Making a mixed yard run on routine
Mixed yards with Toulouse geese stay peaceful when every species has its own anchored routine. Feed at fixed stations so nobody campaigns at anyone else's bowl, let the geese claim their pool and grazing circuit, give smaller poultry escape gaps in fencing that geese cannot follow through, and bring the dog out at times when the geese are settled rather than already stirred up. Routine turns potential flashpoints into background, and most interspecies trouble in real yards traces back to a change in routine that put two animals in the same place wanting the same thing.
Handled with that kind of structure, Toulouse geese become the yard's calm centre of gravity rather than its problem. KinsLe's Care Teams helps a household hold the structure, because supervised dog-and-goose sessions, pool changes, and gate checks can be assigned among family members for each pet, with every completed task marked with a timestamp so nothing relies on memory.
