Our Collie- Ruby- she is a true gem on so many levels. My young adult son had 2 strokes that effected his left side. She often licks his head (he's thinning on top) and his left arm and hand. She did not do this before his strokes and she doesn't do it to anyone else. I have no doubt that she senses there is something off and that he needs help to continue his recovery.
My sons Aussie x Border Collie-River- is such a huge part of his recovery too. He is often on his lap or right beside his chair.
So so thankful for them- I have no doubt that he is further in his recovery than he would be without our furry loved ones.
