Back in the day, yes I do believe they would have been less suspectible to disease carried by rats because the more the body is exposed, the more it builds antibodies to protect against it. But I don't think that holds true today since their use for rat hunting has long passed. I don't know what kind of disease or parasites rats carry that our dogs can get, but I do know that opossums and wild rabbits pose a threat to our dogs.
