I know it’s just a shit post and not the best place for intelligent discussion, but here goes:

You can change their behaviour to spit those things out if you are consistent and always ready.

Always trade items for food and when teaching the drop it command, always reward with something good.

Also, when they have valuable things they can chew or eat, walk up to them and give an additional treat so they associate you with adding value to items instead of reducing value.

You can teach a super drop it command where they get a rare ultra high value treat when they drop what they have and come to you. Have a special word for it.

If you are really consistent with this, your dog migh take this to the extreme by bringing the item to you and dropping it at your feet for a high value reward. Or they go further to give you garbage before you even know about it.

This takes months or years, many years if they have had items taken away from them in the first month’s of life.
