There is no resistance in the back but a bit in the front. She fell out of the sling once and scrambled with all four legs but couldn't right herself. The back legs are tricky because if she sits on them the wrong way for too long she can break her hips just from the pressure. If she tries to get up and ends up in a bad position she can hurt herself but she won't call out.Today is our first rainy day in a while so I will leave her in the shelter rather than hang her up. Lola.
