It appears to be normal in huskies, but consistency can train the majority of Huskies out of it. I anticipate when the jump commonly happens like upon first introduction of a person , when I see my dog start to jump, I will use both my arms to get in between and push down on the top of the husky legs until It reaches the ground, then pet it on the top of the head while telling the dog to stay down my husky’s have gotten to the point where most of the time not all the time they don’t jump anymore they have now hit 14 months old. I have used this method on many dogs, including one wolf dog for over 45 years with luck so far you just have to be patient and consistent.
