Afaik, virtually anything with a sufficiently complex central nervous system is capable of developing aphasia. In the natural world, this does usually mean that their life expectancy drops rather dramatically, which is why it is very rare to see wild animals with it. E.g., a wolf who can't communicate with other members of the pack would soon lose out in group hunts etc. It's much more prevalent in domestic animals and animals in zoos/safari parks, where the conditions for survival aren't anywhere near as harsh.
