Rehoming dog (Cutten)

Boomer is a 4 year old black lab mix that showed up on my doorstep 3 years ago.
He was malnourished had fleas and looked like he had been beaten.
I believe he was left on the side of the road and found his way to my house .
I decided to take him in and nurse him back to health.
For the last 3 years Boomer has been a great dog.
He is very sweet and has so much personality.
He loves people and kids I like to say boomer meets no stranger when he meets new people they are instantly his new best friend .
However he is not suited to live with other dogs or cats.
Boomer would do best in a house where he is the only pet.
My current living situation no longer works for him.
I am looking to find him his forever home so he can thrive.
He absolutely loves to be outside and would be a great adventure buddy.
On the flip side he is also the biggest cuddle bug and enjoys spending his time laying on the couch with you watching tv.
