I want to get a "tune-up" done on Wolfie's back-end, for lack of a better term. Having never done either of these modalities on dogs, I have no idea which one would be better for hip related issues. There is no pain, Wolfie runs like the wind BUT his back-end movement doesn't look 100% to me. Bit wobbly, I suppose?? I know that's an inept description... Anyway, which one should I go with? What worked for you?
