Strange Hair Growing In On 3 Yr Old GD Back

[Nancie & Gracie Doodle]

I don't know where to post this discussion...either here or in the Medical Group.  Gracie Doodle is a 3 yr. old Goldendoodle (F1) and has never had a skin issue at all.  She is a very soft wavy fleece but not thick.  If you push back her hair it is very easy to view her skin.  She has just finished having two surgeries for fox tail removal and was on an antibiotic for 12 days.  That is the only change in her life.  No food changes...nothing.  Within the last week these two areas on her back right on her spin have showed up.  It is almost like she is trying to become a Rhodesian Ridgeback!!  The hair is very course, tight, laying very flat and short.  One is larger than the other.  They are 2/3 back on her back.  Any clues or ideas as to what this is and what I can expect to have happen?

Here is an update on darker hair showing up randomly on your Doodle.  My Graciedoodle is now 10 years old and is still like a big 70 lb puppy.  The hair is what is called "injury hair". It happens when your Doodle gets bruised or has trauma to an area on their body.  Just rolling around and something hard is underneath can cause it.  Gracie currently has darker hair on her shoulder where she had a cyst rupture.  The vet shaved the area and put a stitch in.  The hair is growing out a darker apricot to almost orange color.  So the bottom line is...don't worry, there is nothing wrong with your baby...just some bumps and bruises just like kids!

Oh by the way, the darker hair grows along with the rest of the coat and eventually gets shaved off in grooming.  Meaning, your doodle isn't spotted forever!!
