Opposite of anthropomorphise

To anthropomorphise is to ascribe human features to something, such as an animal. Is there a word that means the opposite, namely to deny a feature exists in an animal because it is assumed to be uniquely human?

For example, some would see it as anthropomorphising to say a dog misses its owner. How would you describe it when it is said a dog can not miss its owner as animals do not feel emotions?

I would think that if you were robbing something of its human characteristics you would be objectifying it:

reduce to object: to reduce somebody, or something that is complex and multifaceted, to the status of a simple object.

That would be zoomorphism:

Zoomorphism is the shaping of something in animal form or terms. Examples include:

• The tendency of viewing human behaviour in terms of the behaviour of animals, analogous to anthropomorphism, which views animal behaviour in human terms
• Art that imagines humans as animals
• Art that portrays one species of animal like another species of animal
• Art that creates patterns using animal imagery, or animal style
