One tiny mosquito can have a big impact on your dog’s wellbeing. One bite from a mosquito can give your dog heartworm disease. Heartworm disease can be a serious threat to dogs; it can lead to lung disease, heart failure, and damage to other organs in the body. It can involve hospitalization with painful injections, which can be traumatic. Prevention is still the best treatment. Heartworm disease is transmitted to your dog by infected mosquitoes, who got infected by feeding on an infected animal. Signs of heartworm disease are lack of appetite, weight loss, coughing, reluctance to exercise, and fatigue. Trifexis is a monthly chewable tablet that protects your dog against fleas, heartworms, and intestinal parasites (roundworms, hookworms, and whipworms). Dogs get internal parasites by eating feces, infected animals, or contaminated toys. Sometimes worms can come directly from their mothers. If worms are left untreated, they can become dangerous and cause blood loss, coughing, diarrhea, weight loss, and inflammation. Fleas may be small, but they can become a big problem in your dog’s life. Fleas are one of the most common parasites you can find on your dog. Dogs catch fleas by being in contact with other animals that carry fleas: they just jump on your dog. They can also catch fleas from eggs that can survive in many environments. Fleas can be really irritating and annoying for your dog. They cause itching, hair loss, and general discomfort, which can lead to worms and even diseases. Your pet can even catch them without leaving the house: this is why the best medication is prevention. Trifexis provides fast relief. It starts killing fleas within 30 minutes, before they can lay eggs, and keeps working to prevent flea infestations all month long. Trifexis contains milbemycin oxime and spinosad, two powerful broad-spectrum parasiticides, that disrupt the nerve transmission within the parasite, leading to the death of the parasite. Trifexis is easy-to-give and comes in beef-flavored chewable tablets. It's like a treat that protects your dog for a whole month. This 3-in-1 parasite protection for dogs and puppies 8 weeks and older and 5 pounds or more, gives you peace of mind. Trifexis comes in six doses for dogs of all sizes.
