Is the layout of whiskers in a dog constant over time, or do whiskers fall out and regrow in different spots? This is a lost dog situation, and there is a foundling that looks very similar but whisker layout seems different. Unfortunately the newest pics that we have of our dog are from about 18 months ago. Could whiskers have rearranged themselves in that timeframe? The foundling is 260 km away, so it's a bit of a trip to drop by and check his reaction.
(To anyone eager to scold us for being lazy or uncaring and unwilling to make the trip, please don't. You don't know our situation).
EDIT: thanks to the kind soul who added better tags, and here's a thousand words worth:
Could the dog on the right be the same as the one on the left, but 1.5 years later and after 3 weeks of being astray? The scar under the eye is a big factor, but there are some differences too. This question is specifically about the whisker layout. The pic on the left is 1.5 years old. Could whiskers have rearranged themselves like that?
