Hello and welcome.My name is Terri.It is my pleasure to assist you today!I am reviewing your question right now.
It sounds like Riley is low in potassium causing hypokalemia:
It causes muscle weakness so the most common symptom is a drooping head.
A potassium supplement should fix him right up.
You can give him some milk and sprinkle a little Mrs Dash salt substitute on his food.
Please let me know how he is doing .
