Angie, our Toto was 16 weeks and weighed 1 1/2 lb. when we brought her home. We followed our Vet's orders to the letter and she has been healthy and just perfect! Dr. Lucy instructed us to keep her out of crowds and not to let her on the ground until she had all her shots. We would naturally take her out, but not in large crowds and we wouldn't allow anyone to hold/touch her. They were very understanding! It's possible that even if we had not followed her instructions, that Toto would have been fine, but why risk it? I think you should follow the advise of your vet. Because Toto is so small, we are still very cautious. Good luck, can't wait to see your little one!!
