I read this short story years -- decades -- ago.
A young woman is spending her last day at home before joining an interstellar expedition to search for non-human intelligence. She lives on a sheep station in New Zealand.
As she prepares for her upcoming trip, she is unaware of the non-human intelligence all around her. The family dogs, who are working dogs, do something complex and intelligent but I can't remember what; the radio reports amazing research on dolphin ?? elephant ?? behavior; there is something else that makes the same point.
The reader knows that the dogs know she is leaving, and that they may never see her again. One is left with the feeling that the expedition will find non-human intelligence, but will not recognize it.
It was probably (95% probability ?) in a magazine, but I cannot absolutely rule out an anthology. Unlikely to have been the 50s. Could have been 60s or 70s. Probably not as late as the 80s. The only magazines I read regularly were Astounding (later Analog) and F&SF. Occasionally I read another mag -- Amazing? -- the name of which I can't recall.
