1.5 year Golden Lab to rehome

1.5 year old male golden lab to give away. Would do best on a farm or a home with no kids and a lot of physical activity. He has shown signs of aggression (nipped) but otherwise he is the sweetest dog. He barks a lot when indoors. We tried a collar with no luck. We had someone come into our backyard uninvited and he has been anxious and barks a lot since. Outside he is an amazing dog! He doesn't bark out there and has never tried to nip outside either. I don't think he does well inside and would be best on a farm. He knows basic commands and is kennel trained. He has had his first set of shots but that's all. He is not neutered. We will be so sad to see him go but with three young kids living in town we know we aren't the right fit for his needs 😢
