  • A medicine he can't rub off!
    Prior to this chewable, I had attempted to use the typical liquid flea medications for my dog child but the wormy little daschund would twist and contort his body all over the rug and my blankets to rub it off. The meds would then maybe last a week on him and he would get fleas...my blankets and rugs however are flea free! Anyways, I finally switched to Sentinel chewables and it has been a huge game changer! I just give him the chewable and he gobbles it all up because he'll eat anything. I haven't seen a single flea on Benji since we switched by on 01/25/2020
  • Works as advertised, easy to administer
    The chewable form makes this medicine super simple to administer; my dog thinks it's a treat! I've had 3 dogs take this chewable and none have ever had any of the issues Sentinel Spectrum is designed to prevent, so I guess it's doing its job! by on 12/09/2019
  • Sentinel Spectrum Chewables for Dogs
    We have 2 indoor/outdoor dogs so the risk of fleas is a little greater than having a single dog. Sentinel Spectrum works great! There is always the risk of them getting fleas from other dogs, but if that happens, we never find fleas on us or in our home. by on 09/26/2019
  • No stress, speedy shipping
    I use Sentinel Spectrum because I have an australian shepherd that drinks brackish water ALL the time. She just got a complete bill of health. 100% well in stool, blood etc. So Spectrum does the job. (I live in Maine and water other than her dish is everywhere! by on 08/09/2019
