Most bad purchases in NCR are not scams. They are rushed decisions made on a photograph, where nobody asked to see the paperwork until after the money moved.
The checklist
1. See the animal live. A video call, not a photo. Photos get reused across listings; a live call cannot be.
2. Ask for the vaccination card before paying. The original, filled in by the vet who did the work. A seller who hesitates here is telling you something.
3. Check the deworming dates. Puppies should be dewormed every two weeks to twelve weeks. Gaps in that record are a gap in the care.
4. Ask the age, and do the arithmetic. A puppy should not leave its mother before eight weeks. If the stated age and the stated separation date do not agree, ask why.
5. Get a real handover date. Not an open booking. A seller who cannot name a week does not have the litter they are advertising.
6. Ask who is delivering it. An animal handed to a general courier for a cross-NCR journey in summer traffic is a bad start to its life with you.
7. Ask what happens if it is ill in week one. The answer should be specific, not reassuring.
The price question
A documented puppy from a known litter costs more than an undocumented one, and it should. The difference is usually recovered in the first year's veterinary bills. A listing far below the local range is not a bargain; it is a missing health record.
