So we recently rescued a new mare on Oahu. She's about 200lbs under weight, had horrible overgrowth on her feet, spurs on her top incisors, matted mane and tail with sticks and wire intertwined in, and cancer on her vulva :( There is something wrong with her RF leg. She won't lock her knee and it is quite a bit bigger then her LF. There is no swelling or heat, so we believe it is an old injury that was left untreated. The strange thing is, her right shoulder seems to be "frozen." Has anyone ever experienced this before? I'll try to upload pics from my phone. She sure is a very sweet girl. BTW, her vulva cancer is assumed to be Squamos Cell Carcinoma. But no biopsy has been done. Has anyone ever dealt with this kind of cancer before? Also, the owner took a hacksaw to her feet prior to us seizing her :/ that was his way of appeasing the Humane Society...ugh! There are other horses on the property who need serious medical care, but we haven't gotten them yet.
