I spent a fortune and lots of time and effort on my garden, and it looked great - and then I got the pup. She ate half of what I'd planted, including my precious grapevine
She also nicked the apples and pears of my budding trees, and trampled and sat on (and so killing) all the border shrubs
I planted some fruit and vegetables, and she ate the cobs of sweetcorn, the potatoes, decimated the strawberries and raspberries... hmm, no wonder she wasn't into Pedigree puppy food
Even though I was always supervising her in the garden, and clapping my hands loudly (I'm sure the neighbours thought I was just a very strange young man) every time she ventured somewhere she wasnt supposed to go, I'd look away for one split second and she'd dig a hole. I'm afraid it's just what puppies do!
I'd say the way forward is never leaving Lottie unsupervised in the garden, always stop her if she goes in the wrong area, or chews something she's not supposed to... and accept that your garden may not be quite how you want it until the little beastie has grown a bit older and realises the things she shouldnt do. Fortunately, by summer, if you persevere with 'garden training' her now, I think she'll be past a lot of the 'destructive' behaviour, and you can enjoy your garden again
