I have two dogs Yoshi (a 2 year old puggle girl) and Roo (an 8 month old Australian cattle mix girl) and they just don’t get along all the time. Sometimes they will fight given certain circumstances (like going for the same toy, being on my lap and being territorial, one being in the bed before the other, or Roo biting yoshis ankle trying to play and Yoshi not wanting to play) how can I train them to stop fighting and not do this to each other?
