First time owner so I don’t know everything. My 30 y/o gelding started doing this a week or two ago but I put it down to bugs but it’s been going on too long now. I’m giving him a super thorough check for mud fever, cleaning his sheath and checking him all over for any bites this evening but what else could it be if the problem persists? I’m guessing it could be A) hind gut ulcers, B) PSSM or C) diet related. My grandad feeds him oats behind my back (yes I have tried getting him to stop and yes I threatened the fact he may kill the horse but he laughed at me), as for what I give him he gets a cup of Pegus Stable Mix (I’m looking to switch him onto a senior feed, if anyone has any recommendations in Ireland I’m down to hear them! That’s what my mam bought him so I just gotta stick with it till he runs out.), 25ml of Devils Relief, a bit of salt to encourage him to drink and occasionally a sachet or two of bute. If anyone has any other ideas as to what could be causing it (I believe it’s pain related, he wasn’t himself this morning) so I can properly discuss any additional concerns with my vet please let me hear them!
