Aussie Butt!

My border collie has a huge poofy aussie butt! Is there anyway just to reduce the poof? She a 9 month old red merle border collie named Reese. I don't have a pic of her butt, but this is her.

First you need to determine if it's live or dead fuzz. That particular region of dog butt seems to hold dead undercoat like nothing else. If when you squeeze that region it feels a little bit crunchy like steel wool it just needs to have the dead undercoat blown or raked out via matt rake.

If it's live and healthy fluff you can thin it with a set of thinning shears or curves.

Sure you don't just have an Aussie?

you can use a Mars Coat King. They work realy well on getting extra fuzzy out! Do a little at a time then run a slicker through the part you did. If you like how it looks move to a different area if not work on it until you get the desired look. Just remember to do a little at a time because you can actually take too much coat out in a short amount of strokes and make them bald!
