Help me guess the breed of my beloved dog loki

Hi everyone, i am having this little guy loki nearly since his birth, i gave no contact of the owner of his parents or anything i got him in a really lucky way, since i am tunisian it is really common for people here to have an atlas sheepdog since it’s the local dog, but the problem the vet told me he is an atlas sheepdog, but since he is growing up more and more ( he is 4month old and weight about 12KG or a little more) i see that his ears are going really up and growing very big and he seems to look like a fox, and since the atlas sheepdog have different kind of ears i am very confused on what is his breed and i might use some help to know, thanks!
