I am not familiar with shots given to puppy litters. My sister just got a Siberian Husky pup(11wks; was told that it was 8wks). The person that she got the pup from claims that the pups has had their FIRST SET OF SHOTS and has been WORMED. Furthermore, he claims that he himself gave the shots and worm meds to the pups. Is it possible for a "backyard breeders" to give those types of shots and worm meds to pups. The place did not look hospitable to say the least.
