From this little bit of information it's really difficult to know why the dogs are continuously fighting. Aggression between dogs can be due to fighting over resources such as food toys or attention, can be territorial or sometimes even affected by hormones. Spaying and neutering and helps in many situations if they are not already fixed. Here are some websites with behavior articles that may help. http://www.veterinarypartner.com/Content.plx?P=SRC&S=1&SourceID=47 https://drsophiayin.com/. Good luck
