Michaela,
>> The bad news is, that it's hard. REALLY hard. On you. This is the ONE time you will have to turn into Lucifer personified. Your dog must be left in no doubt that whatever fun he just had attacking that sheep is FAR outweighed by the consequences.<< I only can agree with that. When our Max chased and killed a goose years ago, I pulled him the whole way home, put him in the garage (he never is in the garage, always in the house with us). He had to sit and stay there on one spot without moving even a muscle for 2 hours, then he was allowed back into the house, only to sit and stay for another 1 hour on his bed. We had no verbal or physical contact with him, only in a sharp voice the commands "sit and stay". Since that day when he goes in to a pond, the ducks and geese can swim around him, he won't even bother to look at them. The hours in the dark, smelling garage he never forgot. But it was very hard on me. You all know, how Bernese can look, when they want to say sorry. Fortunately we never had any problems with sheep, although we live in the country. I think, they are to big for Max. He prefers smaller prey. Martina Stelter Munich, Germany
