My canine companion has long, thick, long hair and missing quite a few teeth. His hair seemed to wick away the topical flea medications from his skin and sprays don’t reach his skin. Some of the combination heartworm/ flea preventative combinations are cheaper than what my Vet charged for the two individual products I was buying before. I bought Trifexis first, but my dog couldn’t chew it, even after breaking it up. My Vet wrote a prescription for Sentinel Spectrum (she doesn’t sell it). This pill is much softer. I give it to him with food (per instructions) & he hasn’t had any vomiting.
