First off, if you don't know what MDR1 is, it's a mutation that's common in collies and several other herding breeds. It basically means there's an issue with the blood-brain barrier that makes it so certain medications can cause severe neurological reactions (and quite often death) in dogs with the mutation.
I did a lot of research before choosing a breeder, and part of why I chose my breeder is because one of the major things she breeds for beyond the standard is MDR1 normal/normal, meaning the dogs don't have the mutation and that they are not carriers (as some claim that carrier dogs sometimes have slight issues with the problem medications).

I didn't tell my vet that my dog was MDR1 normal/normal. The question never came up. She gave me some flea/tick treatment as well as some wormer. And, hey, the wormer happened to be Heartgard, which includes ivermectin, which is like the number one no-no drug in regards to MDR1.
Luckily, I know about MDR1, and again, luckily, if I didn't, my dog is normal/normal, so I can give her Heartgard. But this makes me really worried about any dogs that might come in who might have the MDR1 mutation.
So, to get to my question: Would it be appropriate for me to take an information sheet to my vet to let her know about MDR1?
I just... I would think vets would be aware of this? But since she just gave me Heartgard with no concern whatsoever, I'm not sure. She's super nice, they were amazing, and their practice has gotten awards and they are members of the AAHA. I'm just worried that if I give her the information she'll think I'm ... I dunno. Trying to be a jerk? Acting like I know more? I'm not sure.
What do you guys think? Should I take MDR1 information to my vet, even though my dog is normal and it doesn't actually affect her?
