How can I stop my dog's aggressive behavior?

My dog is very possessive of his toys. I will throw it and then he will take it, lay down, and drop the toy I front of himself. He wont bring it back

My dog is very possessive of his toys. I will throw it and then he will take it, lay down, and drop the toy I front of himself. He wont bring it back to me. If I try to go and take it, he growls and I'm afraid he will bite me. What can I do?

or:u can use the new expensive way , or the old hard way :the new way is taking him to a trainer ,, the old way is that u cut a bit of the dog's tail or ears , just a bit , and make him eat it ,, after he eats it make him smell u for like 5 mins i know it horrible and grosse ,, but its a great way if the dog was very violent and considered as a threat
