🩸 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.
