Do Cockapoos Have Aggressive Traits In Them? My 1.5 Year Old Cockapoo Is Very Food Possessive. What Can I Do?

It’s is pretty much in the question. He has became less food possessive but he still has his moments if I get near him while he is eating. Do cockapoos have naturally aggressive traits in them? He is also on a leash almost all day because we are not sure how to train him to not eat our socks. I don’t want to spank him and I feel like training classes won’t work. Please answer one of these questions. Thank you! By the way if you need details or have questions just ask and I’ll add details.
