Thanks a lot guys
I don't know if it is draining, as I'm living away from home at the moment and Banjo is at our home property. Before the hoof started to rot, we had a farrier out and he didnt even notice the absess hole (cue weird look) until I pointed it out. And he said the same thing, that it was minor and should heal well. But we haven't had the farrier since as Banjo wears his feet down well himself and doesn't need as much trimming as others. I love Banjo dearly, don't get me wrong, and putting him down isn't an option, but he hasn't had the easiest of lives (when I first met him, he was malnourished, underweight, abuse case, with big pus filled holes in his side from spurs, etc) and we want him to have a good life until his time comes. As for asking other vets, the only other vet in the area is very expensive, and honestly, one vet to pay is enough! But if it doesn't improve then I will most definitely get another vet, just in case
