I'm looking for as much information as possible in relation to Heritability of Temperament. I've often heard people talk about how similar a dog's temperament is to it's Dam / Sire and sometimes even the "grandparents". But how much of temperament is inherited, and how much is environmental? I also know that even with a litter of puppies you are going to get a range of temperaments, so not all the puppies are going to be "just like" either parent.
I'm looking for either personal experience or academic studies on the subject. Some of the questions I have are:
What is the greatest genetic distance between two dogs that appear to have a very similar temperament.
What percentage of a litter will inherit temperaments similar to either parent; and how often do the puppies NOT resemble either parent?
Are different traits more readily inherited (i.e. Calmness / Nervousness, Fear / Boldness, etc). I'm looking specifically at Aggression (more specifically at Dominance or Territorial Aggression) at the moment.
I have a few articles already (listed below), but anything else would be greatly appreciated.
- Heritability of dominant–aggressive behaviour in English Cocker Spaniels. Published in APPLIED ANIMAL BEHAVIOUR SCIENCE
- Breed-typical behaviour in dogs—Historical remnants or recent constructs? Published in APPLIED ANIMAL BEHAVIOUR SCIENCE
- Environmental influences on the expression of aggressive behaviour in English Cocker Spaniels. Published in APPLIED ANIMAL BEHAVIOUR SCIENCE
It looks like those English Cocker Spaniels have an anger management issue, lol.
