Just an update for everyone who's hound is on PPA...
Beans started on the PPA just shy of 2 months ago. We were giving him a greatly reduced amount (12.5 mg 2 times a day) and were seeing an improvement. Then we went down to 1 12.5 mg pill a day and things were still good.
Last weekend I watched him eat around the 1/4 pill (we put it in the kibble) and then spit it out on the floor when he picked it up with the last 2 pieces of kibble. I decided not to force it in him. My DH tried to offer him one by hand the next day - same thing - he refused again.
In light of others reports regarding their dogs response to PPA (not wanting to take it, being forced to, and having bad health issues later), we stopped giving it to him. He's been wearing a belly band since Monday and has been doing pretty well - just a small leak here and there.
Thanks to everyone who gave me their stories of hounds on PPA.
