Congrats on your new baby, I'm sure he will be SO much fun!
The "winkie" talk almost made me spit out my morning coffee - ah ha ha ha haaaaaaaaa.
P-Nut's is often wet and I always use wipes after he comes back in - on his feet and his "sanitary areas" as my groomer calls the winkie and tushie. I think the dampness is just a boy thing due to the hair in the area. I remember wondering about it when I first got him.
To take it a little further, right now, his aim is terrible because of a recent leg surgery and he keeps peeing all over his front leg. I practically have to bathe him after he goes pee now.
