I started both my cocker spaniels on Nexgard in June 2016. They have done nothing but scratch & bite. The first month was slight biting, but going into the 3rd month (soon to give pill #3) it’s horrible. The biting, scratching & heavy panting is bad. I don’t like this product at all & I’m really afraid to give them the last one! I’m going to talk to the vet today when I take them in. This product is not cheap especially when you have 2 or more pups! But to have to purchase then have issues! I think the company needs to refund the cost of this product.
