Is it normal for male dogs er "private part" to sticks out frequently?

<p>Although it may sound funny, this is no laughing matter…and I am really trying to find an answer. Not to gross anyone out but our vet said that because it is out periodically, it can dry out and he can develop infections.</p>

<p>It seems that my vet is at a loss as to what to do - and I was hoping to get some advice here.</p>

<p>I get that this is kinda funny but I am in search of some real answers.</p>
