Barylka

Barylka is a dog that Geralt comes across in the quest A Dog's Life. As Geralt traveled down the road east of Oreton he came across a dog being attacked by a group of wolves. Once Geralt kills the wolves he takes a closer look at and notices the dog is domesticated and has a key attached to its collar. He then leads Geralt to a house where there are bandits outside. Once Geralt defeats the bandits, he looks inside the house and with his Witcher Senses he sees that under the floorboards that there is a chest. He opens it with the key on the dogs collar. Inside is a note called 'Druzus the Hermit's Notes'. On it, it says that the dog is called Barylka. The dog had probably lived there prior because there is a dead woman on the ground, Barylka was domesticated and there was a note in the house mentioning him.
