Which of the following can be a result of a severe allergic reaction in dogs?

Severe allergic reactions in dogs can trigger a variety of symptoms due to the body's heightened immune response. One common outcome is blepharospasm, which is an involuntary blinking or closure of the eyelids. This reaction can occur due to irritation or discomfort, often resulting from allergens affecting the eyes.

Epiphora, which refers to excessive tearing, can also be a result of an allergic reaction. Allergens can irritate the conjunctiva or other parts of the ocular surface, leading to inflammation and subsequently, increased tear production.

Both symptoms can manifest during a severe allergic reaction, illustrating how the body's response to allergens can affect multiple systems, including ocular health. In this context, recognizing that both blepharospasm and epiphora can occur as a consequence of such reactions provides a comprehensive understanding of the potential impacts allergies have on a dog's well-being.
