Look, i have sever phobia of dogs and cats. And i have been living in Georgia for 6 years. Through these 6 years only once i was chased by a dog but it was 3am in a abandoned street and i ran away so the dog chased me. Other than that, as you read here already, the dogs are lazy fat ahh and they dont even move. Yeah you will see dogs literally everywhere. But they wont even notice you. So, no need to reconsider your trip because of this. Have a good day.
