I have a Standard Poodle as my Service Dog. She is 2 and I have owner trained her. She alerts me when my heart rate is up which reminds me to slow down. She reminds me when I should go to bed. A few of her trained tasks include helping me when my balance is messed up because of the dizziness, getting my husband if I need him, and picking up things I drop. One of the really helpful things she is trained to do is to lay on top of me when my body is trembling. I have spells where I shake uncontrollably and my husband would wrap me in blankets and put heating pads on me to try to stop the shakes. Now I can have my dog provide the weight and heat. Service Dogs are not for everyone, but can be very helpful. I am much more independent with her by my side.
