Pet Urticaria Symptom Guide | What to Watch For and When to Seek Veterinary Care
Understand possible causes of Urticaria and key points for at-home observation
When wheals appear, record their distribution, size, and duration. If lesions increase rapidly or do not resolve, prompt evaluation is recommended.
What this symptom means clinically
Wheals are transient edematous skin plaques caused by increased local vascular permeability and mediators such as histamine. Allergens or physical stimuli can trigger mast cell degranulation, leading to vasodilation, redness, and raised lesions. Lesions usually have distinct borders and may change or resolve within hours to days.
🐱 In cats
In cats, wheals often appear on the face or ear margins. Lesions may be brief and shift location, and the presentation may sometimes be less typical.
🐶 In dogs
In dogs, wheals are often more obvious and may be accompanied by itching. Lesions can appear in multiple body areas at the same time and may arise or resolve quickly.
