When you get the sling it will be easier. I would use it when she potties, especially then as squatting is hard on their knees. Echo doesn't seem to mind. In fact, she's beginning to depend on us giving her the extra lift, and that's okay, since we're doing this for "the duration", as the vet doesn't think she will improve a whole lot. Poor Sophie is so young to have to deal with this. Just be sure you watch that other knee. Echo's was good when she blew her first one, so her other lasted about 3 years or so, but now it is shot and she is old, so no surgery to fix her, and we'll just keep using the sling. Our best to you and Sophie.
