Lost /lossed

Lost /lossed
 

Good morning,

This question have gave been around to my heard for a few time, because I don't remember what of this couple answer is the correct for the English grammar, I have setted up the word in the google translator but I believe that is crazy or possibly that the translator is incomplete with the preterite verbs, really I didn't know the answer although this kind to question are very basic into of the uses of English language.

What is correct,

Did you find it?

Did you found it?

I have lost the dog in the park?

I have lossed in the park?

What is the loss preterite verb,
In a website where I have been looking for the word it displays me that the preterite is lossed although I'm not very sure,

I will be appreciate with your help.

Have a good day.:)

Good afternoon :D.

I lose - present
I lost - preterite
I have lost - perfect

Loss is a noun, not a verb.

What a great loss! :)

Edit: There are 3 verb forms in English:

1. The normal - I love
2. The continuous - I am loving
3. Emphatic - I do love

The emphatic is used for a question - do you love?

To form a past tense, only one of the two parts of the emphatic form is conjugated to the past:

I loved
Did you love? (not: did you loved?)

And also to form the negative: I do not love

Thank you all for your answer above my question.
