my dog is jealous when my baby sister comes what should i do?

Answers:
You should keep your dog, when your baby sister is around. I know a friend of mine, whose child was been beaten by a dog, because of the same thing. These animals have feelings and they would like to be always in direct contact with their master. Before anything happened, please prevent it.

Work with the dog, when the baby comes home, introduce them. Show the dog that you care about the baby, but do not forget the dog.

Dogs have a pecking order, and packs of them have a concept in which there is a lead male and lead female (the "alpha" male and female.) While your dog may be jealous of your baby sister because she gets your attention, it is also a case of wanting to climb the social ladder.

Try to correct your dog - even if that means sending it away to another room or locking it outside while your sister is there. Eventually, the dog will understand that in order to be accepted, it needs to be in the lower social position for your "pack."
