Hello & congratulations on your new family members. Both dogs need as a minimum, the core vaccines for dogs that include Canine distemper, Parvovirus, Hepatitis, Parainfluenza, & rabies. Depending on the recommendation of your veterinarian, Leptospirosis, Tracheobronchitis & Canine Flu may also be recommended. Since this would be a first time ever vaccine for the dogs, any vaccine administered, except for rabies, should be repeated in 3-4 weeks. All vaccines need to be repeated one year later. Do not forget to discuss with your veterinarian checking the dogs for intestinal parasites, heart worm testing & prophylaxis & using a good flea & tick preventative. Best of luck & thanks for adopting your new friends.
