Today we have been with our 2 in the town to sozialise them and them getting used to noise and cars and people.
The thing is, this time we passed quiet a few dogs today and cobi went basooka every single time. Started barking at them and pulling like hell towards the other dogs.
I was confused what to do. The barking made the other dogs bark and the other owner had to hold his dog back.
To be honest I don't know what to do in this situation.
I tried with no and didnt work. I am scared if I keep pulling him and stuff people will think I'm cruel

What do I do in this situation?
