Are you sure it's not all the dogs thinking they are cats?
Oh, they are each definitely all dog. Except our black lab thinks she's a chihuahua like our oldest dog. Then we have a Belgian Malinois and a mixed breed (part red heeler, part boxer, part

).
Have you ever seen a cat come when it is called? The only cat instincts he has are for hunting. He has now acquired a taste for wild game...mice, lizards, birds, etc.
How many dogs do you have, demik?
