Frightened Cavalier

Okay= first of all relax. They will become friends, but we need to control the bosterious baby in the pressence of our older little girl here. She doesnt understand he is a baby- she just thinks he is big and boysterious and no adult manners. I would suggest, when the puppy is quieter, holding the puppy, just let her get to know him. Control the situations where he could run at her- he just wants to play, to her it looks like a flying clumsy tank coming at her.
Collies are normally pretty docile but that is as adults. As youngsters they can get pretty wild. I actually like your idea of seperate yards to go out. It gives the puppy time to play and gives her a repreieve from his antics. Use inside the house to not only teach him play is for outside but also for them to become friends. This is going to take time.
Also remember when you scold the puppy, the older dog thinks- " see ever since this thing came in here "everyone gets in trouble". There fore try more distraction to the puppy . Start training clicker training. With the older dog, this should be easy. Tell the cavalier to sit, click and treat ( I use cheerios because they are small, quick and they wont fill up on them). Meanwhile work with the puppy. First click then treat, click then treat, - when the puppy understands that noise means something good, start with sit, click treat. Now you have both of them together- with their focus on you and not each other. Say sit, click and treat ( adult dog gets the treat first but be quick..)..
Getting adult small dogs, and big dog puppies will work with some work on your part. I use to have a Affenpincher, a 8 year old with young shepherd pups. Allow the older dog to correct the puppy " leave me alone" ( she wont hurt him- its mostly display) but use distraction as much as possible.
Remember to feed her first. Also if the puppy has to still get extra meal like lunch, seperate some of her food so she can eat when he does too. It wont take long before she realizes that in her mind she gets " more" with this guy around..

A "Border Collie" is an entirely different breed than a "Collie". Border Collies are high energy and NEED a job to do or they are prone to finding their own jobs which could be not to the liking of an owner of a bored Border Collie.
COLLIES and Border Collies aren't much different than any other breed of dog when they are puppies. Puppies are playful. Puppies are babies waiting to learn. I've had lots of Collies in my life but none were "wild" when they were young puppies. At this time I have a 4 month old pup and she's pretty docile for a puppy but the older male is of great help in also teaching her and he outweighs her by at least 50lbs. or more.

It might be of help if you attempt to get them together when the puppy is tired and less wiggly. The pup being only 6 weeks old has virtually no manners if he wasn't taught too well by his littermates and dam. Is the Cavalier normally playful and outgoing? She is afterall a "senior" and has she been around many other dogs in her life? I don't know. If so how did she react? Border Collies as I said above are NORMALLY high energy but are VERY intelligent........VERY. And training him will be your key to not having a lot of frustration with him as he gets older. Border Collies are very active are Cavaliers?
