RB Max got like that sometimes after I took him swimming for several long hard hours.

I would put him in the tub & fill it with warm water. It seemed to relax his muscles. Sometimes he didn't like the tub filling up with water & would fight me, making everything worse. SO I got him to lay in the tub & turn the showerhead on jet with warm water & moved the jet all over his body & he seemed to enjoy that more then anything.

She doesn't need pain pills. Its no good & could harm her anyways. She just needs her muscles relaxed... so go try the shower jet thing & see how she feels... if u can get her to lay down in the tub, she'll enjoy it more. Just make sure her head stays dry or she might get upset & try to run out of the tub thinking shes gonna drown.

& after the tub, dry her off & MAKE sure she goes to bed ASAP & isn't running or walking around. & also keep her quiet the day after if she seems to be stiff in the morning. Giving her all this time to relax will help her muscles te fix themselves & grow stronger so next time wont be as bad.
