Congrats! She's adorable.
If you read any of this, please read the paragraph that starts with 'Remember they really want to please'.
I love mine, he's an awesome boy. I got him when he was under a year from a local shelter.
Here's a list of obvious stuff you already know!
Like everyone else said, lot's of exercise. It sounds like you definitely 'get it'. So many people think it's OK to have a dog as long as they
have a yard. Dogs NEED to go for walks and be outside to explore and sniff new things, especially herding breeds. I live in a condo which sounds
bad, but it forces me not to be lazy (by 6 PM my dog is exhausted and is currently passed out on my bed, probably on my pillow). We hit the dog park
almost every day rain or shine so he can run flat out and wrestle with his buddies for at least an hour. I walk him decently 2-3 times a day and
throw in a number of hikes during the week.
Border Collies really do need a job. At first obviously start working on basic obedience and socializing. You will probably be amazed how fast she
picks up the basics. On a whim I taught rollover in about 5 minutes. I would also introduce a frisbee and ball as soon as possible. It is
incredibly handy to be able to exercise the pup if you're sick or injured (or hungover) and they love it. Basic obedience classes are cheap, you get
paired with dogs of a similar age/aptitude and the trainers usually have awesome tips and strategies for you even if you're no longer a novice. I
think you should do this no matter how confident you are in your abilities because it will teach your girls a TON. Build up to agility or flyball and
you've got a happy dog, girls proud of their accomplishments and will probably have to wipe away a tear or two.
Remember they really want to please. This isn't a breed you want to yell at. If you're not happy with something they've done they feel terrible.
A calm but firm 'No' is usually all it takes. She might test you a little, but it's not the same as some of the more obstinate breeds. Correct
the behavior, give it a few minutes (of heartbreak while she follows you and apologizes with a head on your knee and sad eyes) then reassure her that
she's loved. They're incredibly sensitive and intuitive. This isn't your average dog, they really are amazingly smart and emotional. Yell at
most breeds, they feel bad because they got in trouble. Yell at a Border Collie, they feel horrible because they let you down.
Be VERY wary of her around smaller children at first (when she gets . My dog doesn't know kids at all so I'm super cautious at the dog park. The
breed likes to chase, and while mine doesn't nip heels, many do. Socialization is key, and if she is growing up with kids she probably won't do
this. She will probably momma dog your kids and be super protective of them though. Grizzly bear comes at your family, that dog is going to attack
it and be aware she can't win.
Take her to the vet and make sure to keep up on her shots (I just remembered we're overdue). Trim those nails.
I know it's expensive but you will thank me.
Get the vet to recommend a monthly pill to protect against fleas and other nasty critters. I've
yet to see a flea even though my bud plays with tons of other dogs. Have the vet recommend a good food.
