I've actually "fired" my first client this month. Broad term we use but basically informed them that I would no longer make appointments for his dogs specifically. It took me 30 years to get to that point of acknowledging 'ya just can't do what you used to do'...and that frankly he's a complete assholes (owner) and it's not worth my time . Now I've delt with high maintenance aka assholes clients the entire time but there comes a point and I'm there. Also totting around 130 lb half sedated great Pyrenees has taken its physical toll. Beautiful sturdy dogs these two. But I also enjoy walking upright in the morning. So, weight restrictions hence forth. Frankly should have happened before I hit 50
