I would do the best you can to limit Peanut's activity - hope DH heals quickly! "What to do next" is always a dilemma, one that we have been dealing with for almost a year. Suze has been examined by our Vet and limited activity for a month, (I'm sure she was doing doughnuts in the livingroom when we weren't home!), but when a sore neck appeared one morning out of the blue, we opted for xrays from nose to tail. All negative. More rest, the sore neck resolved on its own but the limp was no better, no worse, just very consistent. The following statements are not an endorsement, just MHO.
I read a blurb on GT about Springtime products; Fresh Factors, Joint Health, etc. and their positive effects on limping so I did a little investigating on my own. While I'm a skeptic by nature, I pride myself in keeping an open mind to new things. So I thought, what the heck? What's the worse thing that can happen? What with holding down a full time job, my elderly parents living with us, 3 dogs, 3 cats and one saintly DH, I don't have an extra minute to sit around waiting for, expecting to see or looking for any little change. Last weekend, after approximately 6 weeks on the new vitamins, it dawned on me that the limp has disappeared. I'm not ready to declare a miracle or petition for sainthood, but I am impressed. But, in the back of my mind, I'm still scared poopless. Suze is going to be 5 on 4/1.
Bottom line is - do what your heart/gut tells you.
