I have a 14 week old puppy and it has been really hard and very life changing.
I work from home and thought I'd take 2 weeks off and then it would be fine. It wasn't.
I know some people seem to go along merrily and it doesn't impact but for us it has been huge.
We now have her at doggy day care 2 days a week so I can actually work, as she doesn't actually sleep that much and so getting any work done when she's here isn't that possible.
The longest I've left her is 30 mins, and that is only a couple of times and when I've known she is shattered. Mostly she hasn't been left and one of us has stayed with her rather than go out as a family.
For the first 3 weeks we did alternate nights on the sofa, as she was up 2-5 times for a wee /poo.
We then had a baby monitor in our room (she is crated in the kitchen happily) and we're up still 2-4 times and morning is at 5:25am. Last night was first time she slept from 10:30pm-4:30am.
Some people do leave them all day with a pop in at lunch but I wouldn't be doing that ever. I imagine longest would maybe be an hour or so.
Re cars, from day 1 we have put her in a crate in the boot, first 2 trips after coming home she cried and howled. But asince that she is fine. We've done 3 hour drives with stops every 30-45 mins and she has been great.
She was toilet trained really fast, but that was as we worked really hard, taking her out every 30 mins or less in the day. She has 4 accidents in total and that was as I hadn't taken her out. She now asks to go out.
I take her to a puppy socialisation once a week which she loves, it's outside and she loves other dogs.
Now the good - she is lovely. And I'm loving the walks in fields and the moments where the training works (recall and sit)
We also have 2 cats and 2 guinea pigs and that has been hectic!
I thought I was prepared. I had read and talked to so many people but nothing had prepared me!
It is a cliche but it is so much about the work you put in too. I see this as a full on commitment. Not just getting a cute puppy, but a project that requires shit loads of work. It is paying off so far. But at 5am when she is desperate to go play with the cats, and you just want to sleep I have questioned the choice!
I am so very sleep deprived at the moment as partner is away working, but that will get better as if I'm not up a load of times in the night 5am is fine.
My experience is probably not the norm, as I look round at others who seemingly just breeze through it!
