Vet Q & A
What OTC flea treatment is safe for my diabetic dog on Sentinel?
Over the counter flea products that are fine to use with sentinel include frontline plus, advantage and Advantix. Just be sure to not bathe your dog a couple days before or after applying any of those products as that can affect how effective they are.

Vet Q & A
My cat has fleas, Sentry failed. What's a fast, safe flea treatment?
Over the counter Hartz and Sentry products do not work. I suggest you get prescription strength flea medications. You can easily get these medications from one of our VETCO clinics inside Petco stores. Here are the ones in your area: ( https://www.vetcoclinics.com/services-and-clinics/clinic-locations-and-schedules/?zip=77081 ) Take the cats with you. It is first come, first serve and there is no exam fee so just the cost of the products. The vet there can advise you when you can give the new product based on when you applied the other product. You also need to treat your house and yard (if you have one for fleas). I suggest these products: ( https://www.allivet.com/p-1389-knockout-es-area-treatment.aspx ) ( https://www.allivet.com/p-9065-vet-kem-yard-spray-32-oz.aspx?SearchTerm=yard%20spray+Auto ) Hope this helps. Best wishes.

Vet Q & A
Need tick protection for dog on Sentinel Spectrum. What's safe?
Hi there! Yes, Advantix would be a very reasonable choice to use along with Sentinel Spectrum. You could also use Nexgard or Bravecto for tick coverage, if you prefer an oral medication instead of topical.

Vet Q & A
My dog needs flea/tick prevention. What's best without sweet smells?
I do not recommend any flea or tick shampoos, these are usually not safe products and not as long lasting as more modern preventive treatment for fleas and ticks. here is the list of the best flea products on the market. Spot ons: Revoulution Advantage Advantage Multi Frontline (ticks as well) Tablets: Trifexis/comfortis Bravecto (ticks as well) - for dogs Collar: Seresto ( (ticks as well) House spary: Indoorex

Vet Q & A
My dog's flea and tick treatment failed. Can I use another one?
Unfortunately, Sentry Pro flea and tick isn't a very good brand, and I would not recommend it. According to the package instructions, it's not safe to give another dose until 14 days after the initial application. I would wait another week, and apply a better flea treatment such as Revolution or Advantage. In the meantime, you can give Peaches Capstar. It's a one time pill that starts killing fleas in 30 minutes and it safe to give now. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. I hope this helps!
