What are the different blood types in dogs?

🩸 The essential dog blood types

Dogs have Dog Erythrocyte Antigens (DEA). The main types are:

  • DEA 1.1 — Most important. Dogs are either positive or negative.
  • DEA 1.2
  • DEA 3
  • DEA 4
  • DEA 5
  • DEA 7

🐕 The one that matters most

DEA 1.1 determines transfusion safety.

  • Negative = universal donor
  • Positive = universal recipient (first transfusion)

🧬 Super‑short summary

Dogs don’t have A/B/O like humans.
They have multiple DEA types, but DEA 1.1 is the key one vets test for.
