Polish Lowland Sheepdog
While they’re strong and durable, Polish Lowland Sheepdogs require daily exercise and have the potential to be aggressive. They can have a high prey drive and chase small creatures that run or flutter. To top it off, they can be dominant and manipulative as they are independent thinkers who make their own decisions. They can get bored very easily as well.
