Great Dane (Johnson City)

Beautiful dog, very sweet not an aggressive bone in his body.
Just over a year old( September 14th, 2022).
He's trained for basic commands but needs work on recall.
He's LOVES to hike, and does well off leash on trails (responds to wait/too far if people are coming so you can leash him).
.
I love him so much and I hate to do this but he needs more room/training than I can give him.
I took him being told they are appartment dogs and he is not, he needs a yard and another (big) dog to play with.
He's really sweet, but too rough for kids he knocks them over and gets in their faces all the time.
Sadly he's much too big for what we can handle.
Looking for a good home.
(If you're a veteran and interested for a service dog/ companion I will wave the fee) Everything he has can go with him, including his broken couch if you wanted it is) I want this to be as easy for him as possible.
If you'd be willing I would absolutely love to see him after he is gone.
I would 100% be willing to dog sit or take him out on hikes if you were out for the day or something.
(My mom is his veterinarian by the way so he has been carefully looked after and has every shot/vaccine/ and preventative that he needs.
He's also microchipped/ neutered/& tacked) $400 obo
