Heeler/collie (Potsdam)

Free 5 month old Male heeler/collie mix.
Very energetic.
Needs to go to a home with NO small children (doesn’t like them running by him he will chase and nip at them), and plenty of room to run (fenced in yard would be ideal).
Likes to chase cats and it’s a hit or miss with other dogs (he has recently started to fight with our females and is getting worse) (NO Small dogs).
He is unfixed.
He is free.
Please know the breed or do a little research before asking about him.
I can deliver within reason.
My mother will be picky as to who he goes to.
He is a very very good pup and deserves to be happy too!
