Once I volunteered to drive someone to a medical appointment, and was asked (by the medical person) how to talk to the patient, due to a language barrier.

(I had at least 2 or 3 workarounds; at that point I'd been dealing with language barriers long enough to rattle off a /list/ from the /top of my head/.)

Same scenario, but cross-species? Or having to explain to the professional the tricks you've picked up for first aid on your different-species buddy.
