do dogs actually like the way anti-freeze tastes? Or is that a joke?

They do, no joke, and it's deadly to them. Never let a dog near an open container of antifreeze.

anti-freeze is a solution of ethylene glycol and water. Ethylene glycol tastes sweet. No joke, and it's also reasonably lethal. The reason it's considered a deadly poison is its sweetness encourages animals (or children) to drink enough to be toxic.

A dosage of about 4 tablespoons is enough to kill some adults. A bowl of the stuff would easily kill a dog.

They do according to a book.

ask the dog heheheeheh

yes dogs love this when it's nippy.
