Dog (Tamed Wolf) stuck in boat

(Samsung Galaxy Tab A) When crossing water with a boat, and a dog (tamed wolf) is following me, he will swim after me, then jump in the boat. However, when I leave the boat and walk away, he won't get out. As if he is stuck. I looked up how to get him out and someone suggested using a fishing pole. So every time I leave the boat I have to hook my dog, which does damage to him. If I'm on an especially long journey he eventually dies. And sometimes I will fish him out, and he will run right back to the boat and get in, even though I'm walking away and am already at a distance. I have tried walking far enough that he would normally teleport and he doesnt, he is just stuck there.
