6-Month-old Golden Retriever

We are looking to rehome our 6-month-old golden retriever, Theodore, to a nice and loving family.
He is incredibly sweet and loves to cuddle, and he is amazing with children.
Our 2 boys both under 3 love to climb all over him and he just takes it all.
Both of our schedules have changed drastically and we just don't have the time to give him the playtime and exercise he needs.
He is completely potty trained and will let you know when he needs to go.
He knows to sit, stay (for a short period), "pound it", and he plays fetch.
We hope a loving family finds him because he is so sweet and has so much love to give.
We are asking for a rehoming fee of $500.
We will also include: his kennel, what will is left of his food, treats, toys, and grooming stuff.
