I'm scared to jinx it, but on Sunday I took Cartman out for a quick 5 mile jog on the jogging path (the woods are closed due to fire danger.)
We jogged and loped and he didn't cough one time!
I had heard him coughing on Thursday when I turned him out after having his shoes reset. I was prepared to call the vet on Monday and report that it wasn't working. But now I am crossing my fingers that we are getting this under control.
I have decided to get a heart rate monitor. I'm paranoid that I might not notice when he is having troubles, and being a TB I can't count on him to pull up on his own no matter what breathing troubles he is having.
I want one that is also a GPS and requires no tech experience to operate:)
