I've been watching this thread and wondering what to say or even if I had anything to say.
Cadbury has taken me to the limit and back more than once. I have told people I won't ever have another labrador. I wanted to try showing with him or obedience or even agility - all of which labs do successfully, even chocolate ones! No chance with Cadbury.
In the first year with him I came home too often in tears because of another dreadful walk or training class, another occasion when he had embarrassed me or someone had shouted at me/him for doing something wrong. I'm tougher now, I don't break down, even after the rubbish walk we had today (chased a jogger, got put back on lead, wrenched my back trying to chase another dog!). But I do know how you feel to a degree.
Because this is the bit where I differ. I love that dog, that stupid, oafish, clown who occasionally makes my life a misery. He isn't the best, he isn't even very good at anything, except he is mine, all mine. I have learned to adapt my expectations. I gave up the idea of obedience and agility, now Cadbury is purely a pet dog. I worked for four years in a pet obedience class to overcome the worst of his behaviour, now he rarely jumps up at people, he doesn't mouth (often), he will respond to his recall if I make sure I catch him before he sees something distracting, he is the perfect foot-warmer and he is my shadow.
I wouldn't go out and buy another 'Cadbury', not even another lab, I would go get another Merlin in an instant. But if anyone tried to take that dog from me they would have to contend with a small ball of fury that would be me coming at them! Some people asked me why I didn't give up, why didn't I just rehome him - that's what a lot of people would do and thought I should do. But I was too stubborn, am still too stubborn, to do that. Our relationship will never be the same as the one I have with Merlin. Merlin and I work as a team, with Cadbury I always seem to be pulling in the opposite direction to the way he is going. Yet, I still see the good behind the bad, the cheerful smile that is always there, the patting paw reminding me labs need hugs too, the impressive beg that took a whole year to teach! See, stubborn!
Sometimes you have to look at what is there and not what isn't. It's complicated, messy, sometimes infuriating, you wonder how you ended up with such a 'hopeless' dog. Only they aren't hopeless, they just need to be looked at in a different light
