Puppy scared of Outside

Puppy fear

My Samoyed girl Zuri is 4 months old now. She used to love walking, I’d take her out 5 times a day to potty train her. 3 weeks ago she heard a loud car noise during our walk and got scared.

At first I tried to force her to walk because I thought she would get used to the fact that nothing is happening to her. Then I saw her get worse and did some research, so now I carry her downstairs and outside, put her down at the end of the road and let her walk home and give her treats when she’s calm. I also play some car noises sometimes at home because my apartment is very quiet and I wanted her to get used to the noise.

I go to a vet uni and I take her with me. She loves uni cos she meets her friends. I carry her to the bus stop and then she’s fine to walk the street from the bus to uni, then I carry her home.

It’s been a few days of this therapy and tbh I haven’t seen much improvement. I let her run around in the uni garden and today she heard a motorbike and got spooked even if she usually feels safe at uni.

Am I doing something wrong? She was so close to being potty trained it’s just so sad to see her be scared of outside when she used to love it so much 🙁
