Wow! You really have a delima. There are several fed flags with this breeder. If you are financialy & emotionaly attached to this pup then you need to go get him. Puppies that stay in wire floored cages develop serious health issues. If your pup is 3 1/2 mo he needs to get out asap. Is there a friend who can keep the pup until you can move?
Its such a shame that these situations develop. Why did you buy from this breeder?
Good Luck
