What do these weird dog and cat interactions mean?

Sounds like they are getting along just fine.  Normal animal behavior. It is the interaction of two different species.

go to your vet and ask.

Why is my dog a cat rapist? Shes too interested in cats, especially our cat we call "******" lol she loves licking his face, feet and asshole. Today my mom complained she cleaned his hole out while she was having breakfast. She does get nasty when he eats her kibble tho

What do you think about my story about my pets? hi im looking for the shitter. Do you know where it is yes follow me the shitter is over here My cat "Fuc ker" follows my dog Shorty to the fireplace and sits on top of it and takes a sh it over the edge casually. I just took a sh it.  Omnmm mmm nmm your sh its so good. I like eating cat food and cat sh it. Dog sh it too. kind of retarded dot lol! wth is wrong with you shorty shut up you useless guinea nigs. All you do is fight and cry for food. Probably why you were givin to us in the first place. Hey fuc ker maybe when im hungry again you can make me dinner. *splurt* its diarhea. Guess u just made me soup.

The signals and behaviors that cats and dogs use to communicate are different and can lead to signals of aggression, fear, dominance, friendship or territoriality being misinterpreted by the other species. Dogs have a natural instinct to chase smaller animals that flee, an instinct common among cats.

It's a sure sign of the impending apocalypse
