Remember the dogs and the puppies. Their natural way of bonding is to roll around on the ground together. With no training, any dog you get will do the same with you - jumping up, paws all over you, tongue all over your face, dive into your lap and roll around. Some people allow that and even like it. But, according to every trainer of canines, you can refuse to allow your dog to be that exuberant. You can require your pooch to not jump on you, and it will in no way cause Fido to think you hate him. Actually, your dog will have more respect for you. If you take Fido for walks, praise him, and give him the occasional treat, he will bond to you.

I forget if you said your sister was married. She has a right to physical touchiness from her spouse, or S.O. She can have that style of bonding with her kids. But think of her as "somebody else's dog." It is not your responsibility to provide her with constant belly rubs and endless scratches behind the ear. She has, or needs to find, a "partner" to meet her need for that stuff. I love all dogs, even other people's dogs. They usually like me a lot too. But I don't roll around on the carpet with my neighbor's pooch the way I might gladly do with my own. I don't allow my guest's dog to keep jumping into my lap.

She is being manipulative by telling you those things. That's like a guy on the first date saying, "I won't believe you like me, unless I can reach inside your blouse." Nonsense! She is just trying to obliterate any boundaries between you and her. What she does is aggressive, not affectionate. She needs "retraining."
