Excellent advice.People should really find out what the dog's breed was bred for, because will tell them what its basic needs and character are; not every small dog is a lapdog, as anyone who has had a Dandie Dinmont terrier will testify! And it is surprising how little people think about grooming, even if the dog is a poodle. I'm sure some people think that its coat grows naturally into a lion clip, and all they have to do is give it a bit of shape, like in topiary!
By the way, I shout "Shut up!" at my mob when they bark, and it works a treat. But that's because I know how they think. To them, for that moment, I am being the big senior dog. I am doing one loud bark for them, and when I stop, they stop. That's what they, and their mother, did when their father was here; they'd look at him. If he wasn't barking they didn't bark, or they'd stop. If he did bark once and stop,, they'd stop because, evidently, the problem was solved. But as a method of 'training' by an owner who is angry, it is not recommended !
