Can I use a second flea treatment with sentinel?
Is Sentinel Spectrum with the active ingredient praziquantel/broad spectrum, just as good as an injection of bimeda injection at vets office?
How long does it take/last for Sentinel Spectrum to kill off worms? It has 57 mg of praziquantel, 5.75 mg of Milbemycin Oxime, and 115 mg of Lufenuron.
I have a one year old golden Pyrenees, my vet suggested putting him on Nexguard & Sentinel monthly. I have read differing opinions, do you know of any dangers with combining the two products?
Giving Sentinel for the first time today. Within how many minutes/hours will I see an allergic reaction if any? Is it common to get side effects from this? Luke is healthy and has never had any worms
I have a almost 14yr old dog who is on 5mg of benazepril and she just ate my father's dogs sentinel for 50-100lbs she is about 45ish lbs. Do i have to worry? Is there any interactions?
Need help figuring out what these small dry spots are on my dog. He’s cavapoo. Is from but bite? Spots don’t seem to bother him. He is on Bravecto and Sentinel.
I have a 65 lbs mixed breed dog. she usually takes sentinel spectrum once a month. through a miscommunication, she took it twice in 3 days. do i need to do anything?
My diabetic dog is currently on Sentinel for heartworm prevention, but I was wondering what kind of flea treatment would be best for her to use alongside it that I can purchase over the counter, so to speak. The fleas are bad this season!
I just adopted a dog at Petco and Humane society had given her Sentinel. Should we keep her on that or can I switch her to Trifexis, since that's what we give our other dog & I already order through Dr.'s Foster & Smith? Thanks.
He was diagnosed with border line positive for heartworm our vet too a micro test that showed negative he has him on sentinel pills he wants to redo the regular heart work test again would it show negative if he is on heartworm pills
Our vet gave us Sentinel to give our puppy. I just found out it does not protect against ticks. What can I use? I don’t want to give additional medicine that would overlap? I will ask vet at next visit. Oh and he’s 4 months old.
