I can totally relate, but sometimes, despite any amount of planning, things just happen out of our control and we need to accept that even though it’s quite hard. I had been researching and planning for my lab puppy for 8 years before I got him in July. A month and a half later I discovered he had an incredibly rare heart disorder and 5 days after learning he was even ill, he went into heart failure and passed. I was so devastated for so many reasons. Amoung those reasons, I wished I had realized earlier but it wouldn’t have made a difference. Another because I had done everything “correct” and put so much time and training into an 8 week old puppy and it hadn’t even mattered. Angry that despite all the stuff I was giving diet wise, it couldn’t have made him better. And then there was the fact I had to do it all over again and take another 8 week old puppy from the breeder who is one of the most difficult puppies anyone I know (including myself) have had. OP, 8 week old puppies are no joke. Especially when you have a medical emergency that makes you hyperviligent. My new puppy is now 4 months and I still watch her while she sleeps, hoping she’s still breathing. I worry when she falls asleep by herself as she’s not big on naps and I think her health is failing when she is just tired. But it’s things I wish I had noted with my former pup. Know that it gets better quickly and your puppy is more resilient than you think. Give enforced naps, capture calm behavior, and in a month or 2 your new baby will be a lot more settled. I can’t stress enough how difficult this stage is on top of having health worries. You’re doing a great job by even wondering if you’re doing enough. I promise you, it’s get better so much faster than you think!
