Could someone give some info on Dr Quack the card game?

It seems you're looking for information about a card game called "Dr Quack." However, there doesn't seem to be a widely known card game with that exact name. It's possible:

* The name is slightly different: Maybe it's a lesser-known game with a similar title, like "Quack Doctor" or "Quack Pack."

* It's a homemade game: It could be a game created by a family or group of friends that doesn't have a widespread distribution.

* You're remembering it wrong: Sometimes details about games can get mixed up over time!

To help me find more information, could you tell me:

* Anything you remember about the gameplay? Was it a trick-taking game? A matching game? Did it involve animals?

* Where did you hear about it? Was it at a friend's house, online, or in a store?

* When did you last play it?

With more details, I might be able to figure out what game you're thinking of!
