Metal Members of my Pack

Just counted. My "pack" numbers 180 exactly. These are the few metal ones, and I'm posting them because they are the ones about which I have questions. Especially the pit bull in left front chasing cat on fence. Was told it is supposed to be a part of a train set-up. Marked Japan. Then there is the dog with the valentine. The dog and house is from England but don't know what year. The bookends and playing dogs rear center and left I don't know if they are bronze or pot metal. Greyhound, in rear right, I would like to know a year. I don't know. I see a dog, I buy it. They all need homes.
