On the morning of a beautiful summer day, a five-year-old, male German Pointer played unattended in the backyard garden. During the following 24 hours the right side of the dog’s face became swollen. The dog developed urticaria and became lethargic, unable to walk and vomited several times.
| Question | Answer | Article | |
| What is your presumptive diagnosis? | Angioedema or anaphylaxis, probably caused by an insect sting. Anaphylaxis can be ‘localized anaphylaxis’ (urticaria and angioedema) or ‘systemic anaphylaxis’ (generalized signs). In the above case the generalized signs should indicate that the disease is systemic. |

| What pathologic mechanism(s) is involved? | Immediate type I hypersensitivity reaction. |
