OooH! A Christmas puppy! Fun, fun, fun! I don’t think a border collie is considered a large breed, is it? IF not, then calcium isn’t that much of a concern. First of all, I’d try to find out what puppy is eating now and buy some. It’s best to keep them on the same food they are currently eating for a while until they get acclamated to their new home. Once things are settled, you can slowly transition to a new food. IMO, it’s not necessary to spend $100 on a bag of food. I choose to buy budget friendly kibble and add a little extra canned, fresh or frozen protein to it to make it more nutritional.
You could always print the best puppy foods list and take it with you to the store to see what is available locally. It would be great if you could post a picture of your pup when you get it. Good luck!
