(Mostly in agreement with stevenjohns.) Menopause seems to be mostly restricted to some primates and whales: > Menopause has been observed in several species of nonhuman primates,[108] including rhesus monkeys[146] and chimpanzees.[147] Menopause also has been reported in a variety of other vertebrate species including elephants,[148] short-finned pilot whales,[149] killer whales,[150] narwhals,[151] beluga whales,[151] the guppy,[152] the platyfish,[citation needed] the budgerigar,[citation needed] the laboratory rat and mouse,[citation needed] and the opossum.[citation needed] However, with the exception of the short-finned pilot whale, killer whale, narwhals, and beluga whales,[151] such examples tend to be from captive individuals, and thus they are not necessarily representative of what happens in natural populations in the wild. > Dogs do not experience menopause; the canine estrus cycle simply becomes irregular and infrequent. Although older female dogs are not considered good candidates for breeding, offspring have been produced by older animals.[153] Similar observations have been made in cats. https://en.wikipedia.org/wiki/Menopause#Other_animals https://en.wikipedia.org/wiki/Menopause#Other_animals
