Charlie,s confidence is gone since a big dog kicked him

Mammy it trying hard to restore it but it will take a while the vet is trying to help mammy as well but when I have a bad day on a walk it´s bad hope I never see that dog again look what it did to me if mammy hadn´t got me on my lead if could have been worse as that dog was breed to attack It´s only takes 1 dog to make me nervous i was excellent with dogs of all sizes before this happened I am not going back to dog training mammy said as I´m excellent when off the lead playing on the beach and having fun hope this never happens to another dog and that I will grow out of
