I personally do not feel a Yorkie should be sold/bought without one. Its inexpensive and I get so tired of hearing "I just dont have the money" You should have money set aside for expenses. I know MAJOR things arise you did not expect but as a safe measure PLEASE have at least 500 $ set aside for testings, sickness, anything that may arise. My Diggy was 800.00 I then had to have bile acid test (breeder didnt want a thing to do with it) $150, 2 fecal exams $40.00 (he came with coccidia) meds for coccidia, blood test, heart worm test, shots, and heart worm preventative. He then was diagnosed hypoglycemic, so then we played the food game lol started on Nutro, then to Innova, then Innova evo, canned puppy food and home cooking. His food alone has cost me over 150$ (trial and error) he has to eat every 3-4 hours so keeping him interested has been a CHORE! Nutrical, Kayro, bullies, cow tails, leashes, harness, puppy shampoo, bed, toys.....I can go on forever.....So thinking you buy a dog for $800 and your done is wayyyyyy offfffffff. I dont mean to sound negative.....but if you really wanna give your baby the life they deserve....set aside FUNDS!!!
