When sitting up, sometimes my DH begins to lean to his right side and so difficult to get him straight again. We took our dog to the vet and when I came out, he was sitting leaning so far he was almost lying down. Guess he needs sides on everything.
MY DH leans to the right or sometimes leans way back from the waist. Usually when he is very tired or more confused than normal. Did I say normal?? Anyway at those times I try to get him seated ASAP because he looks like he is about to fall over.
