Trifexis is a good product for my Chihuahua. I want to stress to make sure to give to your pet on a full stomach as it will cause nausea if you don't.

I have been using Trifexis for the last 3 years when we adopted our first rescue. Our other two girls are also on this product and it sure does work! I was very excited to see the pricing on this website, as it is much cheaper than our vet.

I like that it is once a month. I wish it worked for ticks too. Only drawback is it gives my dog a rash on his belly but nothing that isn't helped by daily Benadryl.

Rated 4 out of 5 by Langel Horrible smell, bad taste
My dog has been using Trifexis since he was a puppy, and I have never had any problems with him taking the pills each month. But, since he has moved up to over 60 pounds, I have to fight with him to get the pill in him. I've tried crushing it up and hiding it in food, hiding a whole pill in a treat, anything you can think of. I cannot even open the package in front of him without him running off and hiding. The larger pill smells horrible, and I can't help but wonder if that is why? My previous dog was on the larger dose, and I had the same problem with him. Does anybody else have any problem trying to get their dog to take the large pill? It's almost becoming too traumatic for both of us to deal with this every month.
