ETA: Her rear muscles in for sure her right rear leg are all twitchy. Both rear legs are trembling. Her tail is almost tucked but not quite. She cannot seem to find a position that is comfortable, getting up and down, moving around.
ETA2: I tried massaging the right rear leg. I can't tell if it's swollen or what. It doesn't feel hot. Mina didn't really like it when I massaged it, which is unusual. I really wish she was more open with her pain behaviors; the only hint I get that she's in pain is she stills when I massage her leg and she doesn't relax her head like when I usually massage. She's also super restless. I've had muscle spasms before and they're both painful and annoying. I'm hoping she just pulled a muscle or something and that's the problem.
I hate this.
ETA 3: Muscle spasms gone after some intense massaging with some lavender essential oil and lotion. We'll see how she feels in the morning. Definitely going to have to invest in a ramp.
What do you folks do for older dogs with muscle/joint weakness? Any supplements other than glucosamine, et. al.?
