Blue heeler puppy needs a great home

My 4 months old blue heeler puppy needs a great home with a yard and those who have the time to properly train him....He does not get along well with children and cats. I have cats, but they're not very good at it, which is why I need to rehome him... He is very active and requires a lot of attention and training...he has all of his shots and paperwork...please don't ask for a sweet puppy if you aren't prepared for a handful, as this breed can be a little much at times...thank you.
