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.

Dog on Sentinel has fleas. What's the best way to treat and prevent?
You're correct that Sentinel is considered a "passive" flea control product - it doesn't kill adult fleas, just keeps their eggs from being able to hatch. Capstar would be quite effective at killing any fleas that he currently has on him. It shouldn't be necessary to wash bedding, etc. since the Sentinel will ensure that the fleas are not able to reproduce. In my experience, some dogs do fine with Sentinel as their only flea control method if they are in an environment where they are rarely exposed to fleas. But if you're seeing fleas from time to time, or if your dog has flea allergies or other skin sensitivities, then I would recommend using an adulticide like Nexgard or Bravecto along with his Sentinel.

My dog is at the weight limit for flea/heartworm meds. What dose?
Sentinel has no tick coverage and does not kill fleas. It only sterilizes the eggs. I always go up a size to be safe as most dogs gain weight but rarely lose weight. It has a good safety margin so using the 25-50 pounds medicine would be best. You will continue to need the Simparica or nexgard with this

Dog on Sentinel has fleas. Can I add K9 Advantix for flea control?
Hello, sentinel has an IGR which essentially prevents immature fleas from becoming adult fleas. It does not kill adult fleas. You can still use an adulticide such as advantix spot on to kill the adult fleas. Hope this helps and best of luck.

Choosing flea, tick, heartworm meds: Revolution, Advantix, Heartgard?
Congratulations on your new dog! I like Revolution if you are looking for a topical product. It consistently works well and is well tolerated. If you like the idea of an oral product better, I like Trifexis (it’s another all in one product). Sometimes though the pets can smell the Trifexis and they won’t eat it. In that instance, I like Simparica and Interceptor. My personal preference is oral products. I hope this helps and please feel free to post any additional questions.
