So, my boy Chrome stopped using his right front leg(it was slightly swollen), was holding it up this week. He has started using it a bit more but now his back left leg he is holding up, and his foot seems stiff. Doesnt look swollen or bruised just stiff and not using. He is isolating himself from the others. I have not seen him hurt himself. Was wondering if something else is going on with him besides him just getting hurt. He still moves around and eats. He is about 10 mos. Old or so. Any idea on if this is something more?
