I have had 3 dobes since 1977...all different.
Tanya was medium prey drive.............super smart
Amy was soft prey drive...............human smart / understood real threat, always a thinker // she had superb filters and used Logic.
Kelly was super high prey drive (off the map).....red zone switch, as a young puppy
- extremely had to flick off, for 10 weeks old
- slow to train & change behavior // brain logic shuts off, when she got ramp'ed up
^^ FM Kelly at 10 weeks old & sons little 8# Male YorkiePoo (Trevor @ 6 years old)...both Alpha dogs.
- both wanted to fight (Trevor was the size of a cat) // and little dog grew up with previous Amy...perfect together
- Kelly dried to injure little Trevor, when doberman pup was 5 months old
- took 1.5 years, before Kelly and little T-Man would sleep together
- we supervised 24/7 when little dog was over..for first few years
- now perfect together (Kelly is 7 and Trevor is 13 y/o), in our no-crate & free roam home // but we LAID THE LAW DOWN
- so we had one OPPOSITE SEX AGGRESSION (O-S-A)
Temperament Evaluation (Low - Medium - High) is Key to accessing RISK, in a multiple dog home.
I have a few rules here, with puppies...Mom is off limits to play biting, that is for Dad.
- Mrs. gets spared.
- current Kelly took 2 months, to leave my hand alone (her pin cushion target)
- former Amy, was an angel, Dad had to encourage her to play fight/bite me / plus play tug and build confidence
I allow ZERO growling, over food with other dogs here...they all share same water & kibble dish (until we went to home cooking).
- and Kelly was not allowed to growl at Dad, if I tried moving her in bed
Now getting those criteria out of the way, when bulling other dogs occur...your pup can be put on a 5 foot leash.
- if your on the computer, put end of leash around your ankle or table leg
- pup has to lay down for 20 minutes straight, before getting up
- if the BREAK is interrupted, the 20 minute stop watch restarts
- they have to learn, to be calm...at times
Socialization...my pups will :
a) see 1000 places & things...experiences
b) see 100 people
c) see 10 dogs
Our last pup was worst case scenario for hackles up aggression ...but we avoided crate & rotate with 24/7 supervision & demanding some law & order...voice pitch & body language, has to be powerful.
- our girl wanted to go after son little dog (8 #)...now she is fine with all good dogs
- but I would never take a puppy to a dog park, when it already nips at the dogs at home
Hope this helps some, just some random thoughts.
