1. Teeth first
Look at the front teeth: two permanent teeth (do dant) usually means the animal has reached qurbani age.
2. Health
Bright eyes, a clean nose, firm walk and a good appetite. Check for ticks and for any wound or limp.
3. Weight and price
Buying by weight? Weigh it in front of you. Compare a few animals of the same breed and size.
4. Pay safely
Only when the animal is handed over — never an advance for an animal you haven't seen.
