Good point, of course, Roger. I chose Trifexis merely because it's so painfully obvious that's it causing serious disease and death.
For a vet to still carry it after all the horrible press it's gotten is just a glaring red flag: this vet is willfully ignoring a groundswell of real people reporting real suffering and even death. That's unconscionable and he should not receive your business.
Readers: you know where I stand on all these poisons. I've written about this prominently throughout the site, so if you've missed it, please search on "heartworm," "flea" and "pesticide" in that lovely little search box, upper right.
And, as Roger so ably points out, set your bar higher than just another brand of pesticide. You can do so much better on behalf of your animals.
