New puppy

My friend, AT, the vet, has been without a dog for two years after the death of Prozac and has just acquired a puppy. Isn’t he sweet? 
He is an Australian shepherd dog actually. At first I mistook him for a Bernese Mountain dog. Perhaps because of his colouring. He is 4 months old and is called Jhappy.
This is what AT has to say:
“Voici mon nouveau chiot : Jhappy ... Non, non, ce n’est pas un Bouvier Bernois, mais un modèle réduit : le berger Australien , plus connu en couleur Merle qu’en tricolore...
Il m’a fallu plus de 2 ans pour me décider à reprendre un chien après mon beau Prozac, mais comprenez pourquoi j’ai craqué sur celui-ci !!!! »
