I will also say that even a HYPP carrier (HYPP
N/H), can have reactions. Several years ago we inadvertently bought a
2 year old QH filly that was N/H. Didn't know that Impressive was in her
pedigree until it was too late. I would never have bought her if I had
known. I'm sure the seller deliberately hid that
fact... We fed her
straight alfalfa hay once (my husband did, actually) by mistake -- it was
the goats' hay. She reacted to it. I found her paralyzed, she
could not get up. It took most of the day before she was "normal"
again. Very scary.
So, yeah, I'd say definitely check her HYPP
status. If Impressive is in her pedigree AT ALL, a simple blood test will
reveal if she carries HYPP, or is positive for HYPP. I sure wouldn't buy
her if she's even a carrier.
Dr Q's advice, always a welcome email in my inbox, brought me to another
thought that I haven't seen covered. Thinking of safety and well being
for horse and rider is to check the pedigree for Impressive in the
background. I had a dear friend go down the side of a small hill when
the back end of her horse went out. Thankfully, both horse and rider
survived. Unfortunately, Joyce no longer rides!
