My dog will not eat or drink water after taking nexgard. My dog has been having chronic seizures and pancreatitis and bladder stones.. my dog personality has changed and acts like he don't even remember who I am or where he is. He can't even *** walk anymore.. nexgard is pure *** posin and I'm telling it like it is, *** being respectful. You *** know this product is trash and needs to be *** banned in America and everywhere.. people dogs are dying on nexgard and the ones that don't die directly from it or killed by the vet because the damn dogs be in so much pain that they have to be put down. Smh User's recommendation: Don't give your dog nexgard, it's like giving your dog bleach or eat posin.
