Allergy

The dog may have eaten or come into contact with an allergen, causing a red rash on the dog's body. It usually gets better after an hour, so the owner only needs to observe what makes the dog allergic and avoid the allergens in the future. If the rash persists and the dog has other adverse reactions, it must be sent to the hospital for anti-allergic treatment as soon as possible.

Conjunctivitis

Dogs’ eyes will be sensitive to light, red and swollen, tearing, and the conjunctiva will be flushed. It is recommended that the owner place the affected dog in a dark place and apply 3% boric acid solution to the affected eye.
