Talk to your parents. I'm assuming they already know your grandmother is allergic to Собаки and that Ты have two of them. They probably worked out some kind of solution with her.
Get your granmother to stay so where else - joke. See if one of your Друзья или other family member could have the dogs. Not far Ты have to chosse between the two.
Try to convince Ты parents to let your Собаки stay in some other room in your house, build them a dog house in the yard, ask your Друзья to keep one или both of them at their place....... I got nothing (if your Собаки are hypoallergenic Собаки then your granmom has no need to worry)
