This product is great for protecting dogs from paralysis tick in the tropics. I have used it on dogs of all sizes, ranging from 8 week old puppies to a 30kg German short haired pointer. I have used it on chihuahuas, basenjis, German shepherds, huskies, mareemas, border collies and more. I ensure that the first dose I give a new dog is smaller (one size class down) and if it is tolerated well I give the correct dose moving forward. The worst symptom that I have witnessed is diarrhea but I am sure to check if the dog has heart worm before I give it due to the risks. Some dogs do not like the smell and taste so it has to be hidden in cheese.

I've been using this for my old labrador. Twice now she's lost appetite been very lethargic and had bad diareha. I'm taking her off this product
Vets report similar cases but it's not conclusive. Suggest that owners keep an eye on their pets post dosing.

I do not understand why this poison is still on the market. Only after reading the many reviews on this poison (most of them bad) that I realised why my dog was going through a monthly phase of vomiting, appetite loss, diarrhea and lethargy. I know now she was suffering after giving her a dose of Nexgard and why she was scratching a lot, could not sleep and woke me up several times at night to vomit and defecate. Negative results of Nexgard outweigh the positive ones. This poisonous product should be taken off the market immediately before causing any more damage, pain and suffering to our pets. Are the manufacturers of this product waiting for a large number of pets to die first before they take this poison off the market?

My dog was consuming another brand of flea and tick oral treatment and still was extremely itchy and suffered with FAD (flea allergy dermatitis). I did my own research and discovered Nexgard Spectra, after consuming my dog had no problems with FAD nor was he extremely itchy! I love this product and highly recommend it! It’s extremely convient due to that fact intestinal & heart working are covered within one chew. LOVE IT!!!

Product does not protect agains fleas and does not kill fleas, my dog had no fleas 3weeks ago, i gave the product as a heart worm treatment with flea treatment 3 weeks ago after a vet checkup which showed no fleas, 3 days ago my house is infested with fleas and today i saw a flea on him. Rang the customer hot line and got a very polite Indian lady explaining a text book answer!!! Useless, now im worried that it doesn't work against heart worm, how will i know? When my dog dies?
