My name is Duke!

Sadly we have decided to rehome our boy Duke. He is 4 years old. He loves all other dogs, cats and rabbits. He has been around both horse and chickens and never had an issue. He is house trained but heavily favors being outdoors no matter the weather.
We have decided to rehome for two reasons.
We have a reactive older dog that really doesnt e being around other dogs so it has been a challenge keeping them separated over the last couple of years. We are rehoming in order to reduce the stress surrounding that issue.
As for children, Duke has only ever known being around kids, infants-teenage. He has recently become very protective of the kids, from reacting when the neighbors are out to taking longer than usual to be okay with friends and family stopping over.
Would love to find him a home with a fenced yard and even some animals to protect. He prefers to be outdoors which has been hard with our neighbors being so close by.
This has been a hard decision, he deserves better.
