Every time I go to ride my boy it seems like I’m finding more and more of these rub spots. I checked the perimeter of the field and found nothing out of place. All the boards were intact. The trees did have rub marks on them like he’s been rubbing on those. I keep treating them and I feel horrible…. Have a greatly appreciate any advice or help on treating my itchy guy. We live somewhere that’s extremely hot and humid with lots of bugs which probably isn’t helping and I can’t put a fly sheet on him or he’ll sweat so bad he’ll almost pass out….
Thank you so much!
