Chuy had a health scare yesterday, and we had to go to the vet. Hopefully it's just a pulled muscle in his back, but there's also the danger of IVDD. He seems to get relief from the pain killer they gave me for him. Hoping for the best.
Update: Chuy has been on painkillers for a week, but gradually he showed improvement in mobility and comfort levels. I think he must have pulled a muscle. Now he's his usual spry, jaunty self, to my delight. :)
