isnt sentinel supposed to be for flea prevention
Can I use a second flea treatment with sentinel?
Can sentinel flea treatment be used for a nursing dog
My dog is on sentinel but I found 2 fleas on him. He doesn't itch or bite so I'm thinking it was something picked up today. What steps should I take next? Capstar and clean/wash everything really well? Should he be taking something in addition to the sentinel to help prevent this from happening again? I originally thought sentinel did prevent this but I guess it just prevents reproduction. I can't bomb the apartment because the windows don't open so I want to solve this ASAP.
I recently had my dog on simparica, but switched back to the seresto collar because I was finding a ton of ticks on him. I completely forgot about his sentinel and when I was asked today at his annual appointment, I went straight home and gave him the simparica, thinking it was the sentinel. When I realized it was the simparica, I gave him the sentinel. Is he going to be sick because of the simparica and seresto collar I have on him? Should I be concerned about the drugs interacting?
hi! my cat, 12lbs. ate my dogs sentinel spectrum (for dogs 2-8lbs)
Hey. I have been giving my dog sentinel chewable for fleas. I don't think it is working so I got nexgaurd instead. It's only been 2 weeks since I gave her the last sentinel dose. Do I have to wait the full month before giving her the nexgaurd? She is just miserable even with daily combing.
Hello I’ve been giving my dogs Sentinel for heart worm, flea, and tick treatment every month. I recently found fleas on my dog, and purchased Advantage/Advantix to treat my cats/dogs. Can I continue to use Sentinel mid-month for heart worm treatment after giving him Advantix for fleas, or would this be an overdose of some kind?
