Our dog has been attracting unwanted attention mainly from male dogs. They spend a lot of time licking and sniffing his genital area and hovering over him. Our dog is submissive, and will always roll over when meeting an unknown dog, which doesn’t help the situation. When my dog tries to get up the dog will run after him sniffing his butt. Some dogs whine while they sniff him. It’s frustrating sometimes because I can’t get them away from him. Is this a hormonal thing or something else?
