There could be several reasons that Ramsey is still scratching himself. One important thing to remember is that not all flea prevention are created equal. The best products for fleas on the market are oral products such as Simparica. Oral products kill fleas within 4 hours. Topical products are generally 12 to 24 hours. When fleas die faster, pets are not bitten as often and usually it’s less. I recommend to discuss starting an oral product with your veterinarian. Another potential cause would be allergies or dry skin and not actually related to the flea you found. I do recommend to treat what you see so treat for fleas. Your veterinarian will also have medication to help stop the itching so that Ramsey is more comfortable quickly. I hope this helps and please feel free to post any additional questions.
