Affected Genes: PRKG2

Variant(canFam6):
chr32:36461302

General Information: Dogs may display aggression towards familiar people for various reasons, including fear and anxiety, conflict, defensive responses, possessive behavior, redirected aggression, status-related aggression, and food guarding.

Likely More Aggressive: Likely aggressive behaviors directed towards dogs that are familiar but not necessarily living in the same household. This can include aggression towards dogs they regularly encounter on walks or during playdates. It is characterized by aggression towards dogs that the subject dog recognizes and has had previous interactions with.

Possibly More Aggressive: Possible aggressive behaviors directed towards dogs that are familiar but not necessarily living in the same household. This can include aggression towards dogs they regularly encounter on walks or during playdates.

This can include aggression towards dogs they regularly encounter on walks or during playdates. It is characterized by aggression towards dogs that the subject dog recognizes and has had previous interactions with.
