The fact that dogs introduce the master in the PSM is clearly demonstrated by the observation that some dogs die to save their master (they are not afraid of death). According to the theory, this can happen only if the masters are on the same priority level with their own being.
There are fights with dogs, when dogs fight to death. It is interesting to see if the motivation can or can't be given by a protection model of the master, or by an instinct, which does not take the master into account.
The elephant
The brain of the elephant could be bigger than the human brain. From this follows that its organization is primitive. A way to explain this is the reduced capacity of the elephant brain to build concept models. If this is true, he uses a huge capacity of the brain to build pure image models. The term "elephant memory" can be associated with this feature. Thus, if it built concept model, the elephant should be able to identify only limited landmarks of the places it passes by. Using pure image models, it memorizes each tree and each branch. This is a totally inefficient mode of brain functioning.
Monkeys
Experiments show that, in a controlled environment, some monkeys build and operate some primitive symbolic models. They might implement this function by software, based on image models. However, these very singular examples prove their incapacity to evolve towards a symbolic model, in fact.
One of the most striking characteristics of these animals is their lack of stability in a model. The most intelligent monkeys are those which have the capacity to stay in a model, when the external reality gives them many opportunities to change the active model. If the monkeys had stability in a model, then they could have better performance at building symbolic models, under the human control.
In spite of the fact that MDT does not sustain the evolution of man from monkey, the behaviour resemblance of monkeys and humans, on image models of course, is striking.
The dolphin
The dolphin is considered a very intelligent animal, next after humans. The dolphin can not only immitate the signs made by humans but they can integrate them into a larger context.
