Great Dane mix

Needing to rehome our Great Dane mix.
He is 1 years old, fixed, up to date on shots, good with other dogs unsure about cats.
He’s been raised with kids but he probably shouldn’t be around kids younger than 5 as he’s big and doesn’t understand his size.
Asking a small rehoming fee of 300.
He’ll come with his cage, food, dog bowls, treats, toys etc.
