My in-laws had a Carin. After a year, the dog started to smell and was kicked outside only to come in for feedings. He would leave the house and the smell would stick around. I know if they had brushed him and cleaned him, the smell would have been less but that experience turned me off from those dogs. The dog lived about 9 years but died after a stoke which took his sight, heading and balance. It was a rough life for a dog living outside.
What a sad story, that poor dog. I have a Cairn and yes she has an odor (not always just after we spend time outdoors) but I keep her clean as possible, I couldn't inagine forcing her to live outside, if it ever came to that (which it wouldn't) i'd try to find her a home where people wouldn't do that. If the dog developed an odor after a year, it may have had a bacterial infection.
No offense to you, but your inlaws shouldn't be pet owners.
I saw this in the community board and thought you all would like to see it. Dogs rescued from a puppy mill and placed in shelters in NY.
