Renats, can you not take them because your apartment does not allow dogs or because they are very active and you don't think it'd be fair to them?

If it's the latter, would you be able to keep them, even if only for a short time while you talk to rescues? Is you ex threatening to dump them at a pound if you don't find them a home?

Is he willing to keep them until you find a new home for them?

Definately check out Amy's links. Good luck!
