I'm sorry for the loss of your rabbits. You probably don't need to worry about your dog. A rabbit disease that kills like this is most likely caused by a virus that isn't able to infect a dog. Chances of your Lab becoming ill are extremely remote.
As you already know, something very serious is going on with your rabbits. I don't know exactly what disease they have, but it is highly contagious with a high mortality rate.
Viral Hemorrhagic Disease (VHD) has been reported in scattered areas of the United States for several years, including New York. It has the kind of mortality you've seen with your rabbits. The bleeding from the one rabbit's genitals would be consistent with VHD. VHD often kills rabbits with very few symptoms present. It is just one possibility. There are also other calciviruses that could be responsible.
These diseases are not treatable, and rabbits that survive can be carriers. If you bought any new rabbits prior to this illness cropping up, that could be the source of disease, and you should notify the person you bought them from of what happened. The illnesses are also thought to be spread by mosquitoes, flies, and fleas.
It's also possible that what your rabbits died from could something else new or rare. Regardless of what it is, it would be a good idea to notify the United States Department of Agriculture. They monitor the serious contagious diseases of rabbits in order to detect any new diseases and prevent the spread of older ones. Here is their contact information:
U.S. Department of Agriculture
Animal and Plant Health Inspection Service
Veterinary Services, Emergency Management

Telephone: (301) 734–8073

Your local Extension agent could also be notified if you prefer not to deal with the USDA. This link will take you to a directory that will help you find the agent for your county:
If your last rabbit dies, it would be good to save the body for a necropsy. If you notify the Extension agent or USDA, there wouldn't be a charge to you.
