Yes, Gidget could absolutely be allergic to her flea treatment! Topical products can definitely cause redness, irritation, hair loss or sores at the application site. They can also cause system reactions such as seizures, tremors and trouble walking but these are rare. Oral products can cause vomiting, diarrhea and decreased appetite. Dogs that have epilepsy may be more prone to have increased seizure frequency but this is also not likely. Extremely rare cases can be anaphylactic reactions of collapse and hypotension and this could be to any product. If you are seeing problems, I would recommend to switch products. While some products have the same active ingredient (like Fipronil), many are different. I have had good flea prevention and very low reactions to Comfortis, Simparica and Revolution. Remember that itching all over can be related to fleas not dying from your product, food allergy or environmental allergies. I hope I answered your question!
