I am so happy that you are seeing great progress in his paws condition. THAT is awesome news.... now if we could only figure out which one or combination did the trick? :)

Please let us know how the CS works.

Our dogs live outside and on extremely hot days they go into the garage where it is airconditioned. It is very dry in Texas and our dogs don't seem to have any ailments so far. They do have a lot of space to run and their foot pads are very thick and resilient. Could it be that you needed a dehumidifier in the house?  Just thinking out loud here.
