Hello Adrienne,
I'm quite new to the site and this forum. First, I'd like to give a bit of background.
My husband and I recently (a week and a half ago) rescued a three year and nine month old German Shepherd mix. He is mostly German Shepherd and we are unsure what the mix may be or what potential percentage. His name is Shadow, and he's such a lovable guy once he's warmed up to you.
The history that we received from the shelter is as follows:
His first and only family, before us, had him since he was a puppy. The father had a regular 9-5 work schedule, and the mother was stay-at-home. They had three kids, the eldest around five or six while the youngest was still crawling. The reason the family gave for surrendering him to the vet was that Shadow was nervous peeing when the father came home. This created problems with the youngest sometimes crawling through the urine. Also, at the shelter, he displayed nervous, fearful, and reactive behavior, especially toward men. In fact, it took four days before he did not bark at us upon return to the shelter, which I was happy to see that he was actually glad to see me return on the day we finally adopted him. He also knew very basic obedience in terms of sit, down, and shake. Other than that, we got to see that he was highly motivated with playing fetch, and was as nice way for us to warm up to him. That's all we were able to learn before adopting him.
After adopting him, I looked up training programs online and came across yours. Other than starting a routine of three walk and three fetch play sessions during the day, we also got him brushing up on his obedience 101. He is leash reactive, so we've been working on keeping him under threshold and doing desensitizing and counter-conditioning on our walks. We even had a very successful session with our nephew yesterday. We had our nephew sit in the field at the High School a block from our house. We walked a half circle around him at first, giving treats liberally each time he was "alert" to our nephew. Slowly we approached, but even if he barked once, we were still able to distract him and get him to do a command. Eventually, we were able to approach our nephew where we pulled out the ball he loves, had him sit and lie down, and then offered the ball to our nephew to toss. With just one or two bark, Shadow warmed up immediately to our nephew.
Because of that successful session, I think we're making progress. I still remain aware that I need to be cautious and methodical though. I want to avoid as many setbacks as possible.
We just have an issue when we have people over at our house. For example, our nephew came back to the house with us, and we had him play fetch with Shadow for a while in our fenced backyard, thus securing the positive association. When we finally entered the house, Shadow remained extremely excited. Usually with us, he'll spend his free time chewing on his favorite ball. He brings it to us, but we just set it down for him as we don't want "fetch" to be an inside thing. We also do our best to capture calm moments when he's inside. However, when someone new is over, he remains excited and potentially anxious. If he is not distracted with something, he tries to mount the new person. He also did this for the first four to five days with us, usually around the hours of 5-8 PM.
What I've been doing is telling him "off" as a command and then get him to sit. I try and wait about a second and a half before I give him the treat, but I'm still worrying that I may be creating a chain command that involves the mounting. I have seen him go to do the mounting, stop, and then look at me. Again, I'm worried that that may have been a sign that he was learning to do that to get a treat. Also, it is rare, but every now and then, during what we call his "anxious hours" (5-8 PM), he tries the mounting with us still. It is definitely not a frequent as it was those first four nights with us. If it occurs with us, I ignore the behavior and get him to do a sit command instead. This is something I am very embarrassed about, but I know that he's still new to us and we're new to him, so he needs time, patience, and consistency.
I'm curious about your thoughts on this mounting behavior and what you think would be the best approach for it. He's doing well with his brain training, and we're on to elementary for him. Other than that, I think we're making some progress with the reactivity, especially with the successful session with our nephew yesterday. However, we still have to work on securing it in several different environments with different stimuli, but we're taking it slow for him.
Hope all is well,
Greg
