Your furbaby has limited protection to these and other illnesses based on his and even his mother's deworming and vaccinations. Deworming should be administered at 2, 4, 6, 8, 10, and 12 weeks old. Vaccinations are done at 6 and 8 weeks and then followed up by two more sets in 3 week intervals. Rabies is done around 12 weeks. Boosters are done every 1-3 years (This is a generally agreed upon schedule by most vets.)
