I honestly don't know how she's going to cope with a puppy. We've always had older rescue dogs who've been fine settling in, but nearly six years ago when the sheep started reaching critical mass we realised we were going to need a sheepdog and got a border collie puppy. I'm used to getting up through the night for a couple of months at lambing time, but toilet training him nearly broke me. He destroyed so much stuff in his first few weeks. I don't have the same bond with him as I do/did with our other dogs because I ended up just resenting him so much for the sheer stress of his puppyhood - he absolutely adores me and I just don't feel the same way about him, it's incredibly sad. But he loves his sheep and he loves me and Mr F and he spends a fair bit of time upside down on the sofa chilling out and he has a home here for life. I'll just definitely be sticking to rescue dogs in the future!
I’m really sorry your loyalty to Jack cost you some other friendships, and well done for removing a negative person from your life. It’s not always easy, especially if you care about someone and have defended them. She talks a lot of shit about Tattle, but I’ve found the posters here to be a lovely bunch, so hope you’ll stick around!
I know preteens aren’t in the game of prising your eyelids open every morning but come on, he’ll have school to get to and whilst we know she doesn’t wake up til gone midday she usually at least attempts to pretend otherwise.
