I scared myself nearly to death last night. For your amusement, I'll let you share my pain xD
I went out to feed Sour and Honor yesterday evening when it was already getting dark (I was a bit late) and noticed that Honor was laying down. Ok, whatever. I scratched Sour's neck a bit then walked over to where Honor was and leaned down to scratch her shoulder, and find it matted and sticky with blood. My hand came back completely dark red and it was all over her shoulder, back, and front leg. Her coat is VERY thick right now because of winter fuzzies on top of baby fuzzies, so I didnt see a gash but with that much blood, it much be fairly large. There was blood on the dirt too. So I immediately freak out (remember, I'm the one that ALWAYS reacts very rationally and calmly when horses are injured...I didn't even gasp when I saw that our colt Peppin had popped his eye out at the beginning of the year...) but I guess since this is 'my baby' reactions are stronger? Honor is still laying down and ignoring me, so I conclude that she's lost a huge amount of blood and is extremely weak. I immediately grabbed her up (miniature mule, remember. She's only 40 something pounds) run with her in my arms up to the front (dude, I'm strong! O_o their pen is in the very back of the property...of 40 acres.)
I sat her down on the deck, call the vet, frantically pacing while waiting for him. By now Honor iwas standing and looking rather lethargic so I was just sure that she was going to go into shock or already had gone into shock and wouldn't make it... frantically trying to think of what she could have cut herself on since I pretty much baby proofed the paddock... but I tried to be tough and met the vet calmly, with all of my medical supplies laid out in case she needed any of it.
The vet rushed over to Honor, knelt down to peer into her eyes, put some gloves on, and started parting the sea of hair to try and find the gash. Nothing. At all. No scrape, no cut, nothing at all. So he got his clippers and started clipping away at the hair (by now it was dark by the way, and we only have two flashlights to work with) but STILL found nothing. He then picks up a few tufts of matted hair, uses his flashlight to look at it better, then oddly enough...sniffed it. And I was just standing there going "WHYISSHENOTHELPINGMYBLEEDINGBABYO_O'. Then the vet starts laughing. HARD.
By now I was totally bewildered and almost about to cry, but then the vet stands up, puts his hand on my shoulder while trying not to cry himself (of laughter) and tells me...
"Its not blood." What do you mean its not blood? What else could be sticky, dark red, and matted?
Yeah. Turns out, Honor had just decided to take a nice roll in a large amount of MULBERRIES that had fallen during the storm that morning and done quite the job on her fur. And after her nice roll, I suppose she just got so tired that she just had to take a nap xD and she was very perturbed by the fact that I would wake her up during her beauty sleep.
Oops? So I've accidently caused Honor to loose a nice, large patch of shoulder and leg hair, and she looks like she's balding very badly. How traumatic for her! LOL.
Thankfully, my vet was very, very sweet about it and didn't even charge me for calling. Said that this was the best laugh he's had in months and it was definitely worth it.
Glad I could help. :3
