| Sounds to me like he was marking his territory, because he was used to having Phoebe to himself, and when she took interest in the Pointer then Riley probably didn't like it. It is normal for dogs of both sexes to mark their territory. It may be a jealousy issue. My dobe gets jealous when my sister's rat terrier comes over, because they are best friends. If one of us picks up Gracie, then Skyler comes over and tries to get us to put her down. Also if my rat terrier tries to even smell of Gracie, then our dobe runs over to get in between them. She doesn't pee or show aggression, but I think that she claims Gracie as hers. |
