I second DP's concerns. All of my dogs have had some sort of problems: Sheltie #1 had under developed kidneys, #2 had Cushing's, allergies, and heart cancer, #3 under bite which caused dental problems, #4 closed tear duck, #5 stomach wasn't absorbing nutrients, #6 broke her knee. All have been spayed except for #6, but she will be. All see the vet minimum yearly which included exam, blood test, and vaccinations. Then there's dog food. #2 had allergies, so we had to put them all on a limited ingredient grain free diet. Not cheap. Then there's dental care. No, greenies are not healthy, and they'll still need cleaning.

Btw, I only have #3, 4, 5, and 6 atm. No plans for another dog for the next umm 5 years! Too expensive and too much time and effort. (And for personal reasons: I want a baby; not another dog).

You might think you're getting a healthy dog. I thought so with all of mine. Only one was not AKC. I'm even friends with the breeder of #3, 4, and 5. Actually, 3, 4, and 5 are sisters but all from a different litter. Yet still, life happens, they get sick or injured.

If you're going to own a dog, you need to be responsible. #6 just had knee surgery. That was $5k! We tried GoFundMe. We got $355 which helps, but we still have to cover the rest. (Thank God for credit cards!). They're our babies, so even if my H and I starve, they will eat.

Another concern is that the main bonding period might be over for you. At 8 to 10 weeks, I think, is the best time to bond with a puppy.

It might be best to focus on seeing your Pdoc over getting this puppy. Maybe life is telling you that that specific dog is not meant to be. Doesn't mean you'll never have a puppy. You just might need to wait awhile. Save up. I'd say save up $500+ cost of puppy. That should cover you for a little while.
