I've read that the side effects of the Bayer Seresto Flea and Tick collar are itching and skin irritations. My dog has experienced severe itching for the last 7 months, while wearing the Seresto collar. She chews, bites, and scratches herself which results in skin irritation (cuts, rash, and hotspots). Do you think the irritation may be because of the collar?

This is not likely to be due to the collar. If the collar were to cause irritation, it would only be around where the collar is placed and would not cause severe itching. Severe itching is often due to one of the following things: 1) Allergies - this can happen suddenly and is usually due to an environmental (i.e pollen) cause. 2) External parasites - fleas, lice and mites can all cause intense itching. It's good to check him for fleas and get other treatment if needed. 3) Over-bathing, or using the wrong product for bathing - Bathing too often can cause the skin to get dry and irritated. Dogs should normally be bathed no more than once a month with a shampoo that is labeled for dogs. If you bathe more than that, or use a shampoo or soap that is meant for people, then you could be damaging the normal protective barrier of the skin. Seven months is a long time for a dog to be itching this much and it must be miserable for her. In order to find the cause of this and give her some relief, I highly recommend you schedule an exam by a veterinarian. We can usually discover the cause quickly and provide the most effective treatment. I hope that helps and she gets better soon.
