Jealous of a Particular Dog

Luckily I have never had that problem unless you count when my boys are both trying to sit in my lap, which ends up with them both there. I do not play favorites or pay more attention to one of them more than the other. In my opinion this is what leads to a jealous dog. Of course I have never had a dog that required more attention because of social or health issues. Situations like this could promote a feeling of jealousy or another dog fighting for additional attention. Pets, not just dogs all need to feel they are equally important and have the same amount of attention of their owners.
