Donald Trump Jr. and Alexandria Ocasio-Cortez got into a rumble on social media after the president’s ­eldest son suggested the Democratic-socialist ideology she supports would lead Americans to eat their dogs.

The meme, posted Thursday night for Trump Jr.’s 1.5 million Instagram followers, shows two photos stitched together — one of Ocasio-Cortez and one of President Trump.

Under the photo of Ocasio-Cortez, the text reads: “Why are you so afraid of a socialist economy?” and under the image of the commander in chief: “Because Americans want to walk their dogs, not eat them.”

Trump Jr. captioned the post: “It’s funny cuz it’s true!!!”

The congresswoman-elect responded Friday that Trump Jr. was trying to distract attention from special prosecutor Robert Mueller’s investigation.

“I have noticed that Junior here has a habit of posting nonsense about me whenever the Mueller investigation heats up,” she tweeted.

“Please, keep it coming Jr – it’s definitely a ‘very, very large brain’ idea to troll a member of a body that will have subpoena power in a month. Have fun!” quipped the congresswoman-elect.
