Agression

Question
"I have 2 female Alaskan malamutes both from the same litter. They are 7 months old. One of my malamutes ( the smaller one ) is very selfish with the food. I put two bowls in there kennel and she guards both of them and wont let the other eat. If the other malamute does she will growl and they both have there haunches up and if Kita goes to get the food while Mya is guarding them they start to fight only for about 10 seconds. Anytime I scold Mya Kita will attack Mya Like she is telling Mya to listen to us and do what she is told. Yesterday I called them into the house and Kita came right in like usual ( she is very obedient ) and Mya took off. 5 minutes later I have to go grab Mya off the lawn ( she stopped and layed upside down being very submissive ) and bring her into the house as I was doing so I led Mya into the house by her collar and I scolded Mya telling her no that she was bad and Kita jumped on her and started to fight. This fight lasted longer than usual so i tried to separate them and Mya bit my thumb nail right off. She didn't do it on purpose she thought I was Kita I shouldn't have intervened. My question is how can I stop that even if i yell no they still go at it with there haunches raised? I Looked at some of your other answers about aggression and i see that it says to favor one to make the other one know she is last in line but we kinda already do that cause Kita always wants our attention so we are always giving it to her. Mya wants attention just not as much. The way I see it Kita is higher rank than Mya but when they eat I see it change. I really don't want them to fight and they are not aggressive towards people or other animals just with themselves I need help before one of them hurts each other

Answer
You have totally misunderstood the rules for establishing rank in a household.  By giving one dog free attention you are essentially heavily promoting her.  When disciplining the lower ranking dog, your promotion will cause the self perceived higher ranking dog to join in.  You have created an "omega" out of Mya.  Being smaller, she most likely suffered at the teat (meaning she did not get access to her mother's milk as easily as the other puppies) and this is why you are seeing food aggression.  The fighting will not improve; it will get worse; one or both dogs will be seriously injured (at best) and you or some other human member of your family will also be injured in the process of trying to control the fight.  You need the IN PERSON evaluation of a certified applied animal behaviorist.  NO ONE can educate you adequately in a text box.  Even with this intervention and with serious behavior modification, positive reinforcement training and a full understanding of dog body language, these dogs will most likely never be able to live together.  Call the veterinary college in your geographical area and get referral to a credentialed behaviorist.  DO NOT bring in a dog trainer.  Get a specialist.  Meanwhile, feed these dogs SEPARATELY, TWICE A DAY.  Do not confine them to the same kennel.  These dogs are both juveniles and this problem will quickly escalate over the next few months.  you might wake up one day to find a dead dog.
