I think it depends upon whether the individuals is an animal lover. Some people just don’t like animals.
I happen to be a animal lover and LOVE dogs. I do think it is a unique selling point. For many it is the only way that get to interact with animals is when the visit the homes of those who are animal lovers.
I personally keep dog treats in my truck and actively look for individuals with dogs so that I can give the dog a treat. I am not able to have a dog where I live so I get to indulge my desire when I am in contact with others who have dogs.
