We have had Stella, our younger doodle, for at least 6 months now. She and our 2 year old male doodle, Seamus, get along fine and the whole showing of dominance thing has seemingly passed....However, for the past week, we have noticed Seamus attempting, again, to hump Stella. (Both dogs are fixed.) I'm talking full on "red rocket" (sorry for the phrase) humping. He had not done this since the first week or 2 upon first bringing Stella home. And even then, it was never real "red rocket" humping (lol I'm sorry but I don't know how else to put this...) We have also noticed that Stella seems to have a bit of a rash "down there" and that seems to also be when the humping started. We cleaned it and it seems to be healing, but Seamus is still attempting to hump and he CONSTANTLY sniffs her there (where the redness is). Could this be a sign that Stella has some sort of infection there or something? We noticed her licking it, but like I said, when we cleaned it, it seemed to start to heal. Is this worth a vet trip? I'm just getting fed up because tonight was just ridiculous and I literally had to pull Seamus off of her.....
