Let me start out by saying ​that if you are getting into these dogs to make money, It's never going to happen. These animals will drain your free time and your wallet 100%. If you want to keep them healthy, you have to feed them quality food. You have to get their vet shots and if you live in the city, you must license your dog. 3 dogs go through a 15kg bag of quality food every 2 week. At €60 a bag, You can see that the feed alone, not to mention vet visits -_- Along with the  registrations make it an almost no win situation. These animals require a lot more attention than most breeds. They will do anything for you. They also absolutely need human affection. Human touch and praise is so engrained into them, That they suffer psychological damage if not given enough of it. This breed is wonderful with kids & people. However, they are a working breed. 2 hours walk or play every day is an absolute must. If not, they become destructive, Destroying their house & crate, toys, bowls or anything they can get their mouth on. They must be given work. These dogs can (supervisioned) get along with each other if raised together, But for the most part, They are very dog aggressive and must be walked on a lead at all times. So, if you still want one of these dogs, be prepared to spend a lot of time with them !!!
