My lab-husky mix is 2 years old and has always been a mommys boy - I'll be 8 weeks pregnant this week and he is acting really off. On our walks he now snarls at every person that walks by, get his mohawk and acts like he's going to attack - SO unlike him, and he's doing things that he used to do when he was a puppy, untrained. Like yesterday he darted outside and ran across the street making 2 cars stop - thankfully they were paying attention. He just seems off and extra extra protective. He has been raised extremely social with dogs and people. I'm wondering if you have experienced this and how to control it assuming it's pregnancy related??
