Get the rest of your pets out of there immediately! It sounds like you have either carbon monoxide or radon in the house. Get a detector for both and have it checked. Do you use an exterminator? Could there be something he is spraying. Has the vet checked for signs of poison? Call the poison control center and speak to them about this. They may have some ideas. If it affects others when they are there but goes away when they are gone then you can bet its something in the air. Dizziness, light headedness, aches and pains can be from carbon monoxide or natural gas leaks. I'd call your local housing authority and ask them to recommend experts that can come and check the house out.
