My 22 week old Aidan has recently started acting more fearful than before. He spooks really easy and will run away with tail between his legs, etc. I took him to a popular place here in TN that has a 3 mile walking path that goes around a lake. I came to a part that has a bridge with the lake under it. A kid came past him on a tricycle and before I knew it, he bolted off and jumped right into the lake! I had him on the leash and was about to go in after him, but thankfully a nice guy came over and was able to pull him out of the water for me. There are a lot of little things that spook him that didn’t before. We socialized him during his critical period, and will take him in stores, walks, meet new people, loud noises, etc. I read it’s common to go through this period. One thing we’ve always had issues with is he doesn’t want to get in the car/truck and will run away when we try to get him to come to the vehicle. He rides in the truck just fine and has been on many trips. Not sure why he’s afraid, but we have to pick him up and carry him to put him in the truck every time. That’s not so bad now, but the vet thinks he’s going to be eventually about 80lbs. He’s about 47lbs and I can barely pick him up even now. He also sleeps with us and won’t jump on the bed, but I realize he may be too young for that. He’s my 1st golden. I’ve always had labs and they loved going on rides and would easily jump up into the car. He’s such a great puppy and we really don’t have any other issues as he’s potty trained and minds really well.
