Geez, those puppy mills make me mad . Um, well, in my house when I grow up, my rule will be "never harm the snakes". I want to breed snakes, and it would be cool to. Anybody who does anything that makes then unhappy--Bye Bye!! Anyway, um, I don't know what to do--did you try putting the iguana in a seperate room, where it can be free, and it could be off limits to the doggies?
