Pregnant mare shots
My mare is going into her 7th month of pregnacy (first foal), I didn't know she was pregnant up until last month because she went into heat three times after I bred her back in April. Anyhow, she got her first rhino shot in her 6th month of pregnancy, should I wait until the ninth month or give her another one in her 8th month and then again in her 10th, since she never got one in her 3rd month? Also someone said that they need a tetnus shot in their 10th month, or do I do all the shots in her last couple weeks?
Also when should I stop riding her? I havn't been riding her hard for the past couple months, just bareback walk, trot, canter, and if not ridden lunged for a half hour. Should I slow down her workout?
