If you dog looks just like a foxhound or a beagle could it be an American bulldog and Rotti mix like you were told?

I FIND THIS A GOOD QUESTION. I HAVE JUST ADOPTED A BEAGLE MIX WE WERE TOLD HE WAS A BEAGLE AMERICAN BULLDOG MIX, HOWEVER I BELEIVE HIM TO BE A BEAGLE RETREIVER OR BEAGLE FOXHOUND MIX DUE TO THE LONG LEGS AND SLIM LONG BODY SO NOT THE EVIDENCE OF A BULLDOG I FIND THIS A GOOD QUESTION.
