First, congrats on getting a dog! Since you asked for advice I think you already have a lot going in the right direction. You're concerned about doing the best for him. Dogs are amazing companions. They are a lot of work sometimes and a big responsibility, but they also always make a bad day better.
My advice:
-Treat your dog like family. He relies on you for his very life. Do what you need to do to keep him safe, healthy, and happy.
-Stay on top of his health with current vaccines, microchip, yearly vet visits, yearly dental visit. If you're able to, look into getting pet health insurance. I have it and it's complete peace of mind knowing that if something happens your pet is covered and you don't have to worry about what treatment you can get. I have Healthy Paws. They have very good reviews. Unfortunately my dog that is still a puppy had to have surgery in Nov that cost almost $8,000. Basically I paid 10% of that, the insurance covered the rest.
-Border collies are the smartest breed, they are high energy and need their mind challenged. Play with him daily, look into training classes, etc. He's likely to surprise you with how smart he is.
Watch videos of Border Collies so you see what I mean about how smart they are (if you're not already aware)
-Feed him good quality food that has meat products listed first as ingredients. Watch his weight so he stays fit and healthy
-Work on teaching him basic manners if he doesn't already know. Sit, stay, no jumping. Not dashing out the door when you open it, etc
-Brush his teeth daily, or at least as often as you can. The health of a dog's teeth reflects what their overall health is and yearly dental visits will extend your dog's life by a year for large breeds and up to 5 years for small breeds. There is also dental additives to add to their water to help the health of their teeth. Wet/canned food is the worst thing for having healthy teeth.
-Look at videos for "teach your dog recall". A good recall can save your dog's life.
