I went to see Filly again yesterday and there is good news and bad news.
The good news is that her hooves look amazing. The frog is much stronger as are the bulbs on the back of the hoof. The surface of the sole looks strong with no cracking. The grooves have deepened and the bars are coming back really well. Also the toes have shortened considerably on both the fronts and the backs. The best looking hoof is probably the front left.
This is ironic as she is also hopping lame on the front left. In fact she finds walking very difficult indeed. We assume that the abscess has flared up again which is a real shame. She was apparently doing very well up until last Saturday when she showed slight lameness. This has rapidly worsened over the weekend until yesterday (Monday) she was very very sore.
Nics' plan was to put her out in the field last night. The fields are wet at them moment and hopefully that will help soften the hoof horn a little to allow the abscess to break out. This is different to the way I've normally seen abscess problems treated, but I trust Nic to be doing what she knows is right. In the end it kind of makes sense to allow nature to sort it out. She would poultice the hoof but neither of us could feel any particular warm spot on the hoof to know where to apply it. In fact the hoof was not that warm at all.
As to her general demeanour, she is just being Filly. We brought her slowly into the barn and she got upset she was separated from her gang of admiring geldings. There were other horses in the barn, but not her particular followers. One of them was brought in and she immediately settled down and went to sleep.
I gave her a long groom and scratch which she accepted gratefully. I also noticed that anytime I went near her left front foot she picked it up clearly asking for the pain to be taken away. It was hard to not be able to help her.
I spent about 8 hours driving yesterday to spend 4 hours with her. Well worth the effort. Hopefully next time I visit she will be a bit better and I can take her for a quick play session.
