Life with a dog is different to life without. I think it's an improvement (massively) but I won't pretend - there are things I miss. DH and I don't have DC so before dogs we used to do all those things childless couples allegedly do
We travelled, had weekends away at smart hotels, ate in whizzy restaurants, had hols abroad, had an elegant home which was clean, fragrant and lovely. No tripe under the pillow, paw marks on the duvet. We had a small, new, clean zippy little car that was spotless inside.
Now our holidays are based around the dogs - usually a week in Pembrokeshire. We have an estate car which is smelly, hairy and muddy. Most of all is that sense of not being able to just bugger off for the day. I love going up to London to see friends or see an exhibition - but can't do this as often as I would like to since it's a drag to sort out dog care. My work options have been curtailed - DH works away a lot during the week so I need to be here most of the time. I've managed to find workarounds that actually suit very well, but it was a damn sight more fiddly. Three dogs (all large, two elderly) costs. Insurance, feed, hydrotherapy, vets bills. More house cleaning, replacing rugs, all the collar porn.
I know that not all our friends and family share our obsession - dogs are not welcome when we visit certain relatives which is fine, but it does limit the time we spend there.
I am convinced of the benefits - life with dogs is immeasurably better than life without, but it does come with its downsides and it's wrong to deny these exist.
Because it's considered terribly unBritish to ever talk about money I think it is the elephant in the room when discussing dogs. Dogs are not cheap. You SHOULD be able to access a credit card or a decent pot of savings in case of emergency and these do happen even to happy, healthy dogs. Other costs should be considered too. And not just now, but when your dog is old. Insurance costs rise as they get older, more frequent vets bills, more treatments like hydrotherapy, often not covered by insurance. Kennels cost money - in peak season like August, it will often cost as much for woof's stay as it would to take an extra child away with you to the sun.
It's relatively easy when you've got a bouncy young dog who loves playing with the kids - life is one long Kodak moment. Now FF 10 years, the kids are teenagers and have left home, and you have an elderly dog that is back and forth the vet, eats money on medication and treatment and can't do all the fun things they used to, is possibly dribbly incontinent or senile - do you really stilll want one? Are you prepared to keep going when this is your dog? Will you be ready to make the last, hardest judgement call of all? This is part of the deal with owning a dog - you have to be prepared, with your vet of course, to take that last step for them.
Personally, I think there is a special place in Hell for people who dump older dogs but sadly it is very common.
Lastly, when they die, unless you are made of stone, you will be utterly bereft and feel like you have lost a combination of your best friend and a family member. And because their lifespan is shorter than ours, you are almost certainly going to have to face this grief and loss.
Sorry, bit of an essay, but I hope it will be something to think about. If you do decide to go ahead, your life will be richer and happier in ways you never imagined.
