I am also a border collie owner who is constantly being told collies are high energy dogs and why have I got one (I actually have 3).
They are amazing dogs. They need a lot of stimulation some exercise, they need attention. A long run each day with your husband will not be enough for most collies.They will need a "mental activity" as well. However that is the fun side of owning collies (if you have the time).
As an experienced owner lock down is a perfect time to get a puppy. Social distancing is the best way to introduce puppies to new situations,looking at life from a distance is a fantastic way to socialise them. It may be harder for a first time owner who will not have the support of a trainer in rl.
Collies do have their own "ways" and do make sure you have a good trainer on a zoom call to help with things that will arise.
Collies do need careful training, they can be reactive, they can chase/herd cars,kids anything that moves. They can herd and nip children,they will chase their balls - they may not be the best dogs to take to watch the kids play football. They can bark at anything, they are bossy, they can be fearful,they are clever (so that makes them easy to train - no it means will learn what they want to learn but are very clever at not doing what you want them to do)
They are not the most sociable of dogs. You dont tend to see collies willingly joining in dog play in the park,herding and bossing the other dogs to stop yes but not enjoying the other dogs company. They can find new situations hard, they can worry a lot before they do things. You never see collies as assistance dogs for example as this would be way too stressful for them.
Collies are not for people who leave them alone for long periods of time -they will go self employed.
I will always have collies but dogs are my life and that is what I like however they are full on dogs who will not blend into the background - you will know you have a collie in the house.
If you are happy to give a large (and I mean large) percentage of your time to a dog collies are fab - if not you may just not have enough time to enjoy the life of a collie.
If your husband wants a dog to run with as no 1 criteria there may be a better fit. (and I will go and pick up this pup instead-
