My RIR legs are injured. Yesterday he was walking funny and not being able to stand well. Today he will not stand at all. Both legs seem to have injuries. The left leg ( that doesn't have the bruising) he will not use at all the other he tries to use a little. What can I do to help him? He is eating and drinking well! I gave him 1/4 of a baby Asprin already. Did he get bit by something or did he get injured? Please help!!
