I've been waiting for a thread like this. Â
Miroslav has a service dog named Masha. She's a borzoi. More specifically, she is a seizure alert dog. She warns Miroslav of seizures before they happen. She will follow and nudge him and will keep doing so until he lays down/gets in a safe position. It's still undecided in the story as to what she does specifically, but as I do more research, I will eventually decide. For now, she is a seizure alert dog.
