My grandma had a nasty little dog that was alway 'hanging out'. He was not
neutered (only god knows why...he was an ugly little mutt) and he would get
infections down there all the time. If I were you, I get your dog neutered,
unless of course, he is a show dog (though I haven't figured out the logic
as to why that should matter in the shows). That should solve the problem
and if nothing else, he'll be healthier in the long run, happier (not always
sniffing for a girl) and since accidents DO happen, you won't have to worry
about him running off (possibly getting hit) and mating w/someones dog, when
there are already to many dogs in the world in need of homes.
