Instead of dogs let us imagine that we are talking about two identical humans.
A materialist ( a scientist who only studies physical things like brains) would argue that two people who are physically identical would have physically identical brains. Therefore,they exhibit the potential to have exactly the same thoughts. So there is no need to transfer consciousness( spirit) because consciousness is just a function of the workings of the brain. On this basis there is no such mysterious entity as spirit or consciousness.So there is no requirement to transfer 'spirit' because if you have a brain then you already have this 'spirit'. However, materialists would deny this is in any way a spirit. They say, we are fooled into thinking there is a spirit but it is just the working of the brain that gives us this illusion.
Opposed to this idea are the substance dualists who want to claim there are two types of things in this world physical; things and spiritual things. The important point from their point of view is that the spiritual things are non-physical. So such things as mind, consciousness or spirituality is actually substance that we cannot detect because it is not physical.
Basically we can say from the substance dualist point of view that physical things occupy the physical world and non- physical spirituality occupies a different world that is not physical. Now despite these two different substances occupying different worlds they do interact.
So from a substance dualist point of view we can argue that two identical humans can have different spirits because spirits are not dependent on any particular physical form. It is also possible to argue from a substance dualist point of view that we have a unique soul.
Roughly speaking the last dualist on the list is the property dualist. Like the materialist the property dualist argues that there are no souls or spirits in a disembodied state that interacts with our physical make up. The important difference from the property dualists point of view is that 'spiritual stuff' cannot exist without a physical brain. Basically, we can say that once the brain dies there is no soul or spirit to carry on a separate existence. It dies with the brain.
As far as identical individuals are concerned from this perspective we can say identical individuals can have thoughts independent on the physical nature of their brains. In other words, despite their brains being exact copies it is possible for them to have different thoughts.
