Seresto will be most cost-effective. It is a good quality product and lasts for 8 months. It would be a good choice for a working dog. Nexgard is as good (safe and effective) as Seresto but it will cost you more per year compared with Seresto.

Seresto is a very good product and in my experience would work best. Otherwise it seems you are doing everything Nina needs. Benadryl and any other medication you are giving should be ideally supervised by your veterinarian. Hope that answers your questions, if not please contact us again!

Hello, & thank you for using Boop by Petco. Yes, you can absolutely place a Seresto Collar on Nala today, if you wish. But please consider that here may be other reasons besides fleas that are causing her to itch. Dogs can suffer from many allergies, just like we can, & sometimes fall can be the worse time of year for this. You will probably need to speak with your veterinarian to see if Nala does have allergies, & not fleas, & what medications will work best for her. Take care.

Typically with the seresto flea collar you do not need any other type of flea prevention. It does take about 24 hours for the collar to start to work. If Roscoe had fleas when you applied the collar i would also recommend giving a dawn dish soap bath and treating the environment. hope that helps

Hello! I'm sorry to hear that Bliss is still struggling with fleas. They can be really hard to get rid of! It is usually safe to give Capstar with Seresto, but if your dog has any medical conditions, I highly suggest that you contact your vet first. Seresto and Frontline used together should not interact, but it's never a bad idea to wait a day or two between removing the collar and applying the Frontline. This is my suggestion for your next few days: First, give Bliss a good bath. I do not recommend using any flea or tick shampoos - a regular dog shampoo or baby shampoo should do the trick. Leave the soapy lather on her skin for several minutes before rinsing, and use a flea comb to get rid of as many fleas as possible. Next, give Bliss the Capstar. Immediately after, be sure to wash all her beds on the hottest cycle. Beds that can't be washed should be dusted with diatomaceous earth or borax powder (away from pets). You can do this with carpets, too. Let the dust sit for an hour, t
