Owning a dog is a complete misery at the moment

It's nearly 6am here and I can't sleep because our sitter has decided last minute that she can only look after my pup from 9am - 7pm this coming weekend after confirming an overnight months ago, which has left us scrambling to find suitable care. I appreciate that because my dog has some stranger danger issues we're working through, his care isn't straightforward but apart from that he's young and healthy (no need for medications at specific times, etc.).

We've had multiple paid meetups with her since December last year to make sure he's comfortable around her. We've been explicit from the beginning that we will be back from this event late at night therefore we would be happy to pay an overnight fee and there is the option of staying in the guest bedroom if she's not comfortable travelling home that late at night. I said this multiple times. I understand that part of it is because she's been unwell for a while and another part is needing to get back to her own dogs but this is an absolute nightmare. We've been planning this for months. She's suggested getting someone else to cover the bit from 7pm onwards but because of his fearfulness of strangers I'm terrified of this happening without our supervision.

We have a backup sitter but she's recently gotten a puppy of her own so I have no idea if she'll be able to pitch in and help at such short notice. We need to be at the venue at 9am so my pup will need to be crated until the main sitter arrives - we already can't be there for one handover, the thought of another one having to happen is just more co-ordination to go wrong and more stress and worry for me. The easiest thing to do at this point would be to cancel the whole sit and miss my friend's wedding (at the very least my partner can still attend). There's just no good outcomes anymore: it's either cancel and stay home or we get sitter cover, we both go to the wedding, I'm miserable and worried the entire time.

It's not just this one off thing though. Actually finding a suitable sitter in the first place was a complete headache and it's been a constant uphill battle with trainers too. We had a trainer who was fantastic for several months but then got sick with covid before Christmas and since then contact with her has just completely petered out. Another trainer offered a six week package so I paid for the initial £115 assessment only to be told that she suddenly had to move to Manchester and couldn't commit to six weeks anymore, but she could offer two sessions in the fortnight that she had to get ready to leave (spoilers: she couldn't, turns out moving cities is a lot). A third trainer talked a big game over messages but it was utterly impossible to organise a session with him at all. As soon as I suggested an actual, tangible date instead of asking for his availability for a third time it was radio silence. Our weekly puppy classes are the only reliable constant in our lives.

It's genuinely put me in a bit of a crisis. Am I the problem? Have we just had fantastically shitty luck? Is this just the industry standard? Like, is this normal and does it just suck for everyone? My mood's absolutely spiralled from reflecting on all this, I love my boy to pieces but if this is the typical experience I just don't think I have it in me to own another dog after this. I want to believe that I'm just tired and cranky and it'll get easier once he's 2 or 3 years old, but right now everything around dog ownership is a miserable, miserable slog.

Other dog owners: please, please share your experiences.
