Male boxer mix (Barton)

I have a 11wk old boxer mix puppy, he comes with papers food and toys also puppy pads and his bowl and lead.
He is a very good boy and we hate to give him up.
We got him for our autistic son but he is too much for him personally.
He is great with kids and people and other animals.
He really is a sweet boy.
He is not fixed.
Asking 300 for a rehoming fee to recoup our expenses.
Send an email I will get it.
Serious inquiries only.
Can send pictures upon request.
He is black and white chested.
