I totally agree with those saying to hold on. If you genuinely want a puppy / dog (they grow up, and they last a long time!) now is the worst time to get one. Especially since you are new to it. Puppies need opportunities to mix with other dogs, to learn both to be sociable and to understand how to behave appropriately with other dogs. This is something that, as a human, you cannot teach them. Dogs that aren't socialised properly can suffer aggression, anxiety, and other undesirable traits. And in an abnormal world full of uncertainty, a purchase now may be not what you imagine it will be.
If your are quite sure that you want a puppy / dog after the lockdown, you will be better prepared if you did your homework now. Start learning about dogs and training. Think about dog behaviors and how you encourage them. Start organising for the new arrival, not just practically, but mentally. Be sure that this is what you can handle, not just what you want!
Then, when the lockdown is over, visit. See the parents, but also see the pup. You can tell a lot about what a pup had the potential to become, especially if you've been doing your homework!
If you are genuinely wanting to become the kind of owner that a dog deserves, then it won't do you any harm to wait a few months and prepare in meantime. If you are desperate and can't wait, ask yourself, is that because of what you want, or because it's best for a pup. You are taking on a baby, and a baby who will be dependent on you for the rest of its life. It will be as demanding as any other baby. Be sure that when you do this, you are doing it for the right reasons.
