The articles above discuss both dog and cat vaccine issues.
This is from Part 2:
Although all dogs are susceptible to vaccine-related side effects, breeds at highest-risk of vaccinosis (in alphabetical order) are:
• American Cocker Spaniel
• German Shepherd
• Golden Retriever
• Irish Setter
• Great Dane
• Kerry Blue Terrier
• Dachshunds (all varieties, but especially the long-haired)
• Poodles (all varieties, but especially the Standard Poodle
• Old English Sheepdog
• Scottish Terrier
• Shetland Sheepdog
• Shih Tzu
Breeds with white or predominantly white coats, as well as those with coat color and pigment dilution such as fawn (Isabella) or blue Dobermans, the merle coat color, blue Yorkshire Terriers, grey Collies, harlequin Great Danes, and Australian Shepherds are also more susceptible.
Note: Breed-susceptibility data are generally unavailable for vaccinosis in cats.
