where do you think dog's behavior roots?

It depends. Frustration aggression does not necessarily lead to redirected behavior toward the handler. It is very common in very high drive Mals and can be useful in motivating a dog to bite and the root is prey. Handler aggression in a dominant dog is an urge to fight for rank/status. So the roots are varied which is why handler aggression is a behavior and not a set trait.

i see :)
if that so then upon picking the pup you shouldn't be concerned about what kind of dogs are parents and what qualities possess that pup.
anyway that's all just a behavior and thus can be easily reversed through training to make any pup to preciously fit your desires.

I take it you’re being sarcastic. I’ll say it again. Handler aggression per se is not genetic. The various underlying causes for it can be genetic such as very high prey drive leading to frustration aggression with some dogs redirecting their aggression toward the handler, or dominance where the dog is trying to establish rank.

It can absolutely genetic. There is one specific, rather popular dog, that is known to pass on handler aggression and it's very well known as well. Doesn't happen very often, but it does exist. It's just like HD. It can absolutely be genetic and passed on through a very specific dog but can also be created through the environment and many other different causes.

Bottom line is, it can be genetically passed on through a very specific dog.

BE please name the dog for we too new & ignorant to magically know. Thank you.

How do you know it’s genetic? What if pups from this dog you said passed on handler aggression were not trained and never corrected? Do you only see this manifested via a correction? And since it is so rare, I would lean toward other explanations.

UC Davis researchers have identified a genetic component to 'adverse behaviours' in the Belgian Malinois, also known colloquially as 'the aggression gene'. The A22 gene is associated with several manifestations, including 'glazing over', episodic biting behaviours and activity levels. A dog with two copies of the A22 gene (A22/A22) is very likely to have negative behaviours, including biting the handler, 'rage', etc. So, in this case, there IS a genetic component to some negative behaviours. Makes me wonder if 'dominance' and rank assertion is related to this gene.

Malinois Behavior

Researchers at the University of California Davis have identified a Poly(A) Expansion in the Dopamine Transporter that is associated with differences in behavior and activity in Belgian Malinois.

The Poly A(22) gene sequence was found to be associated with seizure, “glazing over” behaviors, episodic biting behaviors and activity levels. The findings support an effect of Poly A(22) on dopamine transporter function that is related to activity.

Dogs with 2 copies of Poly A(22) (genotype Poly A(22)/Poly A(22)) were more active than dogs with no copies genotype 0/0 (p = 0.023, Bonferroni-adjusted); dogs with genotype 0/PolyA(22) were intermediate between dogs with genotypes 0/0 and PolyA(22)/PolyA(22)

Dogs with two copies of the A22 gene sequence meant a high risk of high level of activity accompanied by adverse behaviors. Even one copy could be associated with those behaviors.

My question is will breeders actually use this knowledge now by testing for it in advance? Apparently not so far, as that was a 2013 study. Though why? As they are not aware the the study & its findings? Is this sort of testing even available for breeders to actually use?

My friend is looking for a Mal, and has asked prospective breeders specifically about the A22 gene, as her present dog has 1 copy of it (Embark DNA sample analysis, I believe). Some breeders are aware of it and test for it, but still breed dogs with 1 copy of the gene even if they don't know of the genetic profile of the other dog regarding the A22 gene. Apparently, some dogs with 2 copies of the A22 gene have episodic 'rage', even attacking the handler.   Not sure if this is related to rank/dominance issues, but is often expressed when something is being taken from the dog (toy, etc.) or the dog is being asked to do something it doesn't want to do.
