Unfortunately not, the traits of all dogs are determined randomly. There is a possibility, sure, but there are no guarantees. In the case of Rottweilers, the unique perks of this breed allow you to strengthen the "True Friend". However, it is possible to get such buffs without getting the "True Friend" trait itself. Don’t worry, it doesn’t mean that these perks are useless. When crossbreeding dogs, you can choose the option "Inherit traits". With a lot of luck, during the next crossing, the new puppy will be able to get the "True Friend” trait as well as its buffs!
