Praying for you, for comfort, healing, peace.
Dogs DO tend to know when we aren't well. I had a dog who would body block me from going near my husband. He would whine and bark, act totally jealous of I tried to kiss my husband. It turns out that the dog could tell when my husband had developed serious infection. Eventually my husband died of infection. But the dog's posturing gave us a heads up that something was wrong. He was classified as a service animal as a result of his behavior. He was a pit bull.
Perhaps that dog will be your clue that treatments are working, or give you early warning if they aren't...catch problems in the bud. But no matter what, draw close to God, and stay there.
As an American you have the right to not believe in guns. You also have the right to not believe in God. But if someone is trying to break into your home, or wants to harm you, the first thing you will do is pick up the phone and call someone with a gun. The second thing you will do is pray that they get there in time. ~Don Moore
