My name is Finn!

I got Finn as a puppy and I do not know what exact breed he is. He is a sweet, gentle, even tempered dog. He loves going to the beach, hiking, and playing at the dog park. Finn loves children and even plays with toys more gentle with them. He never barks at other dogs and the only time he does bark is to alert me someone is coming to the door. But it never goes on more than a few warning barks and he will stop barking when I ask him to. He knows sit, lay down, roll over, play dead, high five, and shake. He is a very smart and intuitive dog. He likes treat puzzles. Finn does have separation anxiety. I am looking to rehome Finn as I no longer have the capability to give him what he needs and that is regular exercise, and not being left alone for long periods of time. Someone who works from home, or can bring Finn to work is the best candidate for adoption. Someone who has a yard or access to a dog park/field to play is a must.
