Hehe getting more complex!!!! I think if the dog was bought by the money that came from selling the cows then 1 Goat=1 Chicken+1 Dog will be correct However case here is not so, the dog (money) was came from Rambo's personal pocket, so he is giving away money so, 1 Goat-1 Dog=1 Chicket+1 Dog will be true Am I right?
