Yes, for sure. Any animal kept from its natural environment and harvested for its material resources is a slave.

Doesn't matter if humans thing they're cute, tasty, or necessary. We literally enslave other living beings in order to feel good about ourselves.

Pets are emotional slaves. People keep them because of the emotional value they provide to their lifestyles.

In the past, though, dogs (domesticated wolves, however you want to look at it) were more akin to 'hunting partners', wouldn't you say? But for you the line is crossed when we start keeping them in kennels/breeding them, I guess?

No, actually the line is crossed when people who keep slaves are dishonest about it.
