Has anyone with a male neutered dog had a similar experience to this: Hamlet's "peen" seems to be exposed much more frequently than it ever had been in the past. Initially, it seemed to be food-related after he got his appetite back and, quite frankly, the BF and I were a little bemused thinking that he must be REALLY happy to get some food now that he's eating again. But, the past few days, it seems to occur at non-food related times. It's not that it never happened before but it just seems kind of random. Maybe I'm overanalyzing but I just want to be sure this isn't related somehow to the cancer and have it addressed. I did note it in his log I take to the oncologist and while she commented on other items in the log, made no comment next to this one. Should I be concerned about this or is this just a boy dog being a boy dog? (I grew up around all female dogs as a kid.)
