She was very well behaved and quiet, so I put my oldest child on her, still on the lunge line. I had him work on walk/halt transitions and change of direction. They both did great and there was no silly stuff from Filly. After about 15 minutes, we called it a day.
Next, it was spa time. D and I gave Filly a good bath and painted her face and ears with Swat. Her sweet itch is at a minimum, and she didn't seem too miserable and itchy this time. I read an on-line article recently about putting a mixture of baby oil and scarlet oil on the mane and tail of horses suffering from sweet itch to prevent the midges from biting them. It sure seems to work! Below is a photo of her tail which has been treated with the mixture. She has not been rubbing in the last week, so her tail is growing back nicely.
Filly has rubbed her mane only a little bit - you can see how it is thin near her shoulders:
She has no sores or bare patches on her ears, shoulders and croup as she did before:
The dogs were in the woods, so Filly is in her alert stance:
A little more relaxed:
