2 year old male dog in need of a great home (Prescott)

I need to rehome this very sweet boy.
I was told he is a blue heeler mix.
He’s around 35 pounds.
I’m not sure what his background was before I got him, but he is a bit timid around new people.
He has really warmed up to me however and is extremely loving and well behaved.
He plays really well with my puppy, very submissive, shows no aggression in the slightest even around food, is very calm, listens very well, and is potty trained.
He has all his shots, is microchipped, and fixed.
He just needs a loving home! There is a small rehoming fee.
