That is mad hour I’m afraid. I’d never had it before with previous puppies but this one turned into a Tasmanian devil in the evening. My daughters Miniature Schnauzer was the same. I found my puppy (Whippet) was worst when she was on the sofa. My other dogs had never been allowed on the sofa. She’d started puppy classes and I found that, when I put her collar and lead on she would behave better. I thought I’d been sold a monster, but the trainers at both training classes we took her to, knowing dogs far better that me, told me I had a good dog, and they were right. The training classes were the making of her. She understands far more words than my other dogs ever did. I would eyeball her, touch my nose and say ‘behave’ when she was being extra naughty. Even now, at nearly 5, at mad hour she wants to do her training with treats: sit, down, turn, round, lie down, heel, wait, stay, paw etc. There was a very good programme with Clare Balding about dogs the other night that gave some really good tips. I don’t know what channel it was on. When my daughters mini was extra naughty at mad hour the would all get up and leave the room and ignore her! I think I spent a lot of the first few months in tears and would have given her back if I could have but she’s amazing. I’d love to be able to go back and have one of those mad puppy nights again, knowing how she was going to turn out. I do think training classes asap are the way to go. We did go to one that didn’t suit either of us. It was outside with too many distractions for a sight hound and the were only interested in dogs that with gold standard potential.
