Hi Sangtea, 1.have you ever got a died dog 2.have you ever got a die dog Let's clarify your meaning. I assume that you are asking someone if he or she had a dog in the past, and the dog has passed away. It sounds unnatural to write "died dog" or "die dog". If we want to describe a dog which is no longer alive at the moment, we can use the adjective "dead". Example: He is going to bury the dead dog. Of course, we can also use "died" as a participle adjective in this case, but we have to modify our sentence structure. Example: He is going to bury the dog which has died. / He recalls fondly of his dog which has died two years ago. If we write: "Have you ever got a dead dog?", it is very unnatural too, as the question is asking the reader if he or she has kept a carcass in the past. Back to your sentences, you can simply write: "Have you had a dog?" By using "had", native speakers will be able to infer that you are referring to a dog which has passed away. Hope this helps. Cheers

Have you ever had a dog die. This may be what you're looking for.
