Can my dog die if it drinks water that drains from an a.c. unit?

Can my dog die if it drinks water that drains from an a.c. unit? Good question and one that as we come into summer, becomes even more relevant. So can your dog die if they drink the water that drips out of the bottom of your AC? No, but letting them do this is not a good idea so don't let them! My own dog has drunk water from my AC unit before and been ok, but I have always stopped him from drinking right away so each time he has done it, he has only drunk a little bit of water. If you would like piece of mind on this issue, why not give your vet a jingle and ask them for their opinion?
