And if one is the son of a carrier, but not a carrier himself, carrier is the worst you're going to get. I'm suspecting if your breeders were knowledgeable enough to test for it, they were probably also knowledgeable enough to breed carrier to clear instead of carrier to carrier (I'd ask, though). Unlike many things, even dogs who are only carriers can have problems with certain meds, but not as serious as a dog who is affected. It's just something your vet needs to be aware of so they don't use the wrong drugs.Can someone please explain to me what MDR1 is?
All I know is that one of the puppy's parents is a carrier and the other is a son of a carrier so I'm a bit confused on what it is?
Is it something serious that I should stay away from?
