Free dog (Wentworth)

Male blue/red heeler Fixed 5 years old Is very smart, but was an older man’s dog that did not work him so he is very excitable and wants to be busy! Would be best as an only dog or a dog in similar size that doesn’t mind being bossed around.
Has been around children, but probably best around older children as he gets excited and wants to rough house.
He has been in a fenced in yard his whole life so that would be the best setting for him.
He is very interested in cats and chickens so I would say to keep him away from them.
He is a very sweet dog just very energetic and needs to be an only dog or someone that can train/ work with him!
