TY for your honest participation and answer. When looking at behavior all professionals will look to science for the best answer as of today. What I would suggest is asking how would this make the dog boss? Did someone ask the dog: “Hey why you walking in front” “me boss”….
Joking aside but it is the truth nobody will ever know what a dog is thinking! We as humans are in a cultural fog thinking that dogs are trying to rule over us humans. Which will always come to the one term/label and that will be dominance or alpha!
To keep this short dominance is used in the wrong context by many humans and some professionals.
No scientific proof of a dog walking in front means they think they are boss!
