What applies to dogs also applies to other humans. Do you go around 'not knowing' whether other people might be p-zombies, or do you normally operate under the assumption that other people have subjective qualia comparable to your own? Probably the latter. Little leaps of faith like these are necessary to avoid the tarpit of solipsism. And as for your dog, wondering if your dog really loves you or if he's just a piece of meat mimicking the appearance of love to get food is not a recipe for a healthy relationship with your dog.
Avoiding the anthropomorphism of animals is important when you're actively researching animals. But otherwise, leave that attitude in the lab.

Not sure why you bring that up, because that is not really an assumption, it's almost the definition of a species. And otherwise: yes. But again: realizing that it would be an assumption is healthy, imo.
But otherwise, leave that attitude in the lab.
Sorry, but hard no. It's not even an attitude, it's realism. Can you please try to understand that it's perfectly possible to realize what anthropomorphism is at all times, yet at the same time take great care of pets and have a typical pet-human relationship?
