So i will apply these methods! I'll get back to you in a few days. His recall is very very strong now. Ive added a few modifications and pushing for more distractions. On a hallway around 30 feet ive recalled him with the female in the way, my wife, food & 3 of his favorite toys.
I think this is happening.
"Setting hormones aside, it can sometimes still happen that a male dog may instinctively feel the need to act protective of a female dog if she is perceived as a resource that is worthy of protecting. The male dog may have a strong emotional attachment to the female dog (he plays with her, has strongly bonded with her), but there may also be still some elements connected to instinctive competitiveness over the mere fact that she is a female."
I will try to see the thresholds of my dog before doing anything else.
Female is ok. Just need to work more on her focus with me & stop the way she reacts to other dogs. I do thank you for all the knowledge you've pass to me!
