I can see a long coated dog looking pretty scruffy in a short amount of time, especially out on the streets in inclement weather, puddles, dirt, mud, etc. and weeds like 'beggar's lice' etc. But then, I puppy sit for a show coated Shih Tzu and it takes her no time at all in the leaves to look neglected. Plus, there's the way my two Yorkies look when they finish 'plowing' after being freshly bathed and primped...the first few times...
I am so glad your family was able to find the owner.
