Injury Question/Help
[Edit: My pictures kinda suck : / I wasn't prepared for an injury when I went there so the quality suffered lol. It already seems that this lump thing is a mystery, so I will be waiting to see what my vet says about it!]
Sorry for the sideways! The top part of the cut is normal, but the big yellow pus thing is what's confusing me. I thought it was just excretion, so I was going to wipe it away, but it's actually like...attached? I don't know how to describe it really. It's like a big lump of pus almost growing out of the end of the cut. An abscess? The wound is also oozing like crazy. His knee was perhaps a tiny bit swollen and a tiny bit warm, but almost to the point of it being unnoticeable. His gait seemed fine and he was in a good mood as we walked around and trotted lightly for a bit. Here's a couple more pics; tried to zoom in some but they aren't that great since they were by camera phone.
Thanks!
