Beautiful McNab read post thoroughly

Hello, Let me start by saying this is not my dog so please don’t send me hate messages.
My niece has a beautiful McNab Cattle dog she has a full time job and is moving out and into a small apartment and cannot take him with her.
We cannot keep him as we already have two dogs and he needs a lot of attention.
He is unfortunately diagnosed by a vet and with OCD and other aggression issues.
He is very sweet once he knows you well and loves to cuddle.
But due to aggression problems he is not able to be around small children or strangers until he gets to know them, as he will nip hard if he is in an unfamiliar situation.
Due to his OCD he gets fixated on things, squirrels, shadows embers from a fire ect and if he isn’t distracted or kenneled he will continuously bark at said objects.
But here’s the thing I truly believe if he was with someone who could spend the time with him and had a job like herding cattle that he could be an excellent dog.
He really is a total love once he knows you, If you’re interested this will take time you’ll need to meet him and grow a relationship before you take him home.
He is free to the right person.
