No harm in getting your thoughts in order, regardless of how things turn out with OH

The following points are my thoughts and experiences, I have one middle aged (working) collie and have had her nearly 18 months now. She's my first dog, but I do tend to read around a lot and "absorb" ideas from watching friends etc.
I'm incredibly lucky - she's so laid back I suspect she's "special"

this means she can be left at home without destroying anything, she travels pretty well, she's good with other dogs, her recall is 90-95% spot on, she is loving and cute...
Other collies are always on the go, can get obsessed very easily with a ball or a toy or other animals (sheep, livestock), or chasing cars, or chasing lights/shadows.
It's a fine line between genius and madness as they say.
Heaven for my dog would be trundling around at my heels all day, snuffling about in the field as I faff with a water trough etc, with some playtimes with other dogs.
I have used bite inhibition on friends' pups and it seemed to work - basically when the pup nips in play, you "yelp" then sulk - copying what a littermate would do. Takes a bit of time to sink in, but you're doing this while they're still babies.
My dog's very sensitive, so I am careful with my tone of voice, and I make sure not to stare her down. Any reprimand is a gruff "no", then a light and cheerful "come here then" / let's go do something fun. I'm not a bully, but I'm not a soft touch either. Gentle insistence on things like giving her pills or trimming her claws - a bit parental if you like.
Other dogs will cheerfully put up with you screaming blue murder while they eat a rotten fox corpse
Obvious things I didn't necessarily think of:
Make sure you can carry and lift your dog, or have reliable help on hand. God forbid something happens to them and you need to get them off your field and to the vet, into the car, etc. Worth practising so they're not too wriggly.
Days out, visits to relatives etc - can you take the dog? Can you leave them safely in the car? Is it too hot/cold for that? Just needs some negotiation and planning. My girl is scared of strangers, so "babysitting" doesn't really work out.
Public transport - rules vary, and dog might be terrified (mine hid behind my knees - her default setting).
Poo - lovely thought! But at least one deposit a day, that's a lot of poo bags in landfill, or can you set up a dog poo wormery....think about fencing them out of your fruit/veg patch, but then they'll poo on your garden path just in time for the postman.... Bitches' urine kills grass too.
As a farmy-outdoorsy type you'll be used to mud, muck and hair, but it's worth repeating. I can take my boots off at the door, but no matter how long I shut her in the kitchen to dry off, she always finds something to smear along the hallway
Hope that's a little helpful!
(I can't believe how short a time I've had her, but she's with me for good now)
EDIT - there are "bargains" out there. I got an incredible "deal" for a working dog because it was a gamble due to her shyness etc. Don't discount a dog with issues - they may not even *be* issues for you if you're a good match. Same applies to rescue dogs etc
