(eg. description of the frequency and severity of the symptoms
On September 17, 2016 the dog developed alopecia and erythema. On September 21, 2016 the dog's alopecia worsened. On September 22, 2016 the owner called the Animal Product Safety Service (APSS). The APSS veterinarian stated with the Zodiac Powerspot, the flea and tick drops, and the Zodiac Flea and Tick Spray, permethrins and pyrethroids can cause a tingling sensation to the skin, as well as redness, dermal irritation, and pruritus. The APSS veterinarian also stated occasionally animals will develop sores or scabs, and alopecia secondary to scratching or biting the application site. The APSS veterinarian additionally stated some animals are more sensitive to the ingredients than others. The APSS veterinarian further stated signs often resolve after bathing and with topical applications of vitamin E and cool compresses, but may take up to 24-72 hours. The APSS veterinarian finally stated s-methoprene is an insect growth regulator (IGR) and primary concerns from topical administration are for mild dermal irritation and redness, usually from the carriers. The APSS veterinarian stated with the flea and tick collar mild dermatitis, mild agitation are possible. The APSS veterinarian stated with the medicated shampoo significant clinical signs are not expected. The APSS assistant advised the owner per the APSS veterinarian that the symptoms seem to indicate flea allergy dermatitis rather than any reaction to the products used. The APSS assistant also relayed that the topical spot on products can cause alopecia in some pets, but that is usually limited to the application site. The APSS assistant recommended bathing the dog (with liquid dish washing detergent (LDWD)) to remove the product as a precaution, taking the dog to the veterinarian (to discuss other flea preventives that would be more effective), have the veterinarian call for information, and calling back with questions.
Minor
The APSS veterinarian stated that the Zodiac Powerspot, the flea and tick drops, the flea and tick collar, the medicated shampoo, and the Zodiac Flea and Tick Spray were not considered to be related to causing the clinical situation. Flea allergy dermatitis suspected. Incorrect dosage applied to the dog.
