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.

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

Thanks for using Boop by Petco! If you are talking about a praziquantel injection, I think the Sentinel is a much better option. The injection burns and it only treats one type of parasite. The Sentinel treats many. I recommend the Sentinel. Kisses to Penny!

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.

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.
