I have no idea what to do. It must've happened last night or while I was at school, and when I came home Tango had a cut on his hind leg right around the fetlock. It looks fairly deep and it's fairly bloody, but the blood has dried and isn't flowing anymore, the part that's worrying is the fact that the cut and the area above the cut is swollen, like big swollen lumps on his leg. I haven't touched it or messed with it, I've moved him into the paddock and I plan on cold hosing him as soon as someone is home to help me (he and water don't get along too well) but other than that I have no clue what to do.My first reaction was to call a vet, but my parents refuse, my mom wants to see what happens to it by tomorrow.
He's standing fine, resting that leg a little bit, but when he lifts it his leg trembles and when he steps he wobbles and hobbles around, I don't know how to apply bandages properly- I've never had to deal with this, and I honestly just don't know what to do.
