i took Duke in and he was given a cortisone shot to stop the itchiness. that seems to have worked for now, but i don't like the effects. when he was younger it used to make him urinate without even knowing he was. he's older now, so he can get by with minor dribbles, but it's terrible because he's so reliable and so aware of when and where to use the facilities. he seems so embarrassed by it, but luckily the problem wears off in a few days. he was also given an antibiotic to clear the rash, which appears to already be showing signs of relief. i'm going on a mini vacation and when i get back, i just may have to switch his food over again. stupid call of the wild.
