Haha! I'm almost glad to see this post!
I think Lucy is about at the same point. I haven't missed too many days of grooming, but I swear a rainfall and just an hour or so of wearing a coat and her dang armpits and chest are COMPLETELY matted. I swear I am also at the point of going out to buy show sheen and was trying to find advice for and against it! So funny that your timing placed your post here and today!
Do you think the show sheen is working well for you?!
I have also considered the "S" word and when I talk to Lucy while grooming, and she's showing her displeasure at the tangles, I say "I bet you're just sitting there yelling in your mind, JUST SHAVE ME ALREADY!"
Can't bring myself to that point yet, but I bet she might like it..
Also her beautiful tearless eyes are tearless no more. I've noticed that she tears a lot worse when stressed or going through a really tangly spot in her coat. Poor doggee!
Good luck with Sandy, and please do keep us updated!!!
