Of course, I am not a vet and no expert on Blue Borns, butttt....my Cali is 5 years old and super healthy and now titer her when it is shot time. Other than rabies she has not gotten any further vaccines in the last 3 years.
Since you don't take Mack anywhere I would wonder about the need to immunizing him at all, or wonder if he needed the protection more than another dog might. Really tough decisions!
Would. Vet school be more likely to have someone who could think this through with you since Blue Borns are so rare?
Do keep us posted -- Mack is so remarkable in many ways
