First Time Dog Owner

Hello!

I am a first time dog owner, and my boy (neutered male) is an all white husky German shepherd mix (probably). I got him from a rescue, and he will allegedly be six [edit: years old] next month. I have had him since October, so about five months now and things have been going pretty well, we have good days and bad days.

Today was a bad day, and I just wanted to talk about it and maybe ask for some advice? I was feeling super low energy today and no matter what I did Apollo (my dog) would not settle. We go for an hour long walk in the morning, then he gets a ten minute walk around lunch time and an hour at the dog park in the afternoon then we just went on a thirty minute walk/run/training sesh to see if he would chill to no avail. Still up in my face asking to play. I am not sure what to do, so I put him in his crate, which I never really do because I feel bad about crating him; throughout the day he has full run of my apartment. He has also gotten more vocal, beginning to sort of bark at dogs to get them to play with him and bark at me when he wants to play; which I do not like. He is also getting more daring about stealing food off the table and in general more… bratty?

Any thoughts would be so appreciated!!! I am not sure what to do to help him.
