Mom's pain is now mine

Since Mom hurt her shoulder she has not been carrying me up and down the steps! Instead, at bed time she makes me walk up the stairs with my leash and collar on so that in the morning she can put it back on and make me walk down the stairs! Why must I suffer? With the leash and collar on I can't race into my crate and grab the cookie! Mom drags me back and makes me sit and wait for her to take off my collar! So unfair.
