Poor Poor Rusty!!! I hope he gets well soon!
I've never had a dog that had to have his anal glands expressed

Let alone, infected!! The poor thing!
I know when Mojo was very sick for about a week, his little behind was very raw and they told me I could use Destin? ---the baby diaper rash stuff.
They wanted to put one of those cones on my Rusty when he had his stitches in his back...but I told them no way....those things are just too weird...but hey, they work though!
Hugs to you Rusty!!
