Dog’s jump to tell you something.
Ex: When my Aussie was a year old, I was taking him for a walk and there was a house being built… he started jumping on me… now why would my dog who I have positively trained not to jump, start jumping? I 1st looked at my dogs body language… his body language told me he was nervous about something. Then I looked to the environment… something new and noisy was occurring (construction). So I used “touch” to get his mind focused on something else, while we moved past… using treats and praise for doing what I asked. Once we got far enough away, he had calmed down and was good. When we had to walk by again (we live on a cult-a-sac and the new house was at the end of our street) he was a lot calmer and was not so anxious (no jumping).
With this post… I really want to challenge you to pay attention to your dogs body language and see if your dog is trying to tell you, “Help! This thing in my environment is making me nervous!”
