dominance issues with old dog and pup, Charmhaven NSW

Ive got a 5yo male Maltese/shitzu and my family decided to get a puppy for our children. We got a 8wk old male tenterfield terrier x kelpie. The first few weeks went really well they were sharing toys and a kennel even though he had his own. In the last week Ive noticed the behaviour getting a bit more persistant and strong. this morning i woke to distressing yelping from the pup, i went out to find the maltese chasing the pup relentlessly and if he caught him would try to savage the pups groin area. Now the maltese is desexed and the pups only old enough now. We have a huge yard and there are plenty of toys and places to go.What can I do as it really distressing for me and I cant keep the maltese locked up in the laundry forever. Please help me.

ANSWER: Dominance issues with old dog and pup
Having dogs of the same sex will always heighten the struggle for leadership within the 2-dog pack. Being a KelpieX the young one is independent, will get more attention than the older one - as he is still a puppy, so jealousy builds and bullying starts as soon as there is no more supervision. The puppy also - given the breed- will find it hard to 'stop' and relent - and therefore adding to the pressures he puts the older dog under. No more preferential treatment for the pup, and use both hands, one for a pat for each dogs. Ensure the older dog has some private time with you when the pup is sleeping; watch anything that may cause a fight, eg favourite toy, food, attention etc. Things should settle down with proper leadership and consistency and fair interaction. If persists, get professional help.
