If you go over to Elvis' calendar, you'll see the last two weeks is just rife wit Torbutrol.
Normally I'd see that as a really bad thing, but not in this case. For the last 10 days or so, my dachshund bitch, Haley, has had a discharge. A couple of days ago, that became a full blown season (well, as full blown as a 14 1/2 year old bitch can have), so Elvis coughing has a really understandable and external cause.
The Torb is knocking what he gets easily, and he's not had to have more than 1 a day. I suspect that until Haley goes out, Elvis will continue to fret and get coughing spells. As long as they're knocked fast by the Torb, I'm not going to worry.
His weight is up a bit, too, but he's been on some decent pasture the last couple of weeks. Since he can't be exercised, it takes a bit longer to take off. Fortunately, it's actual weight and not water weight gain causing the problem. So I'll just keep an eye on that.
