MilbeGuard is an oral tablet prescribed to control and prevent intestinal parasite infections in cats and dogs. Dogs and cats 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. MilbeGuard prevents heartworm disease and kills roundworms and whipworms found in cats. MilbeGuard prevents heartworm disease, controls hookworms, and kills roundworms and whipworms found in dogs. Heartworm disease can be a serious threat to dogs and cats; 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 cat or 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. MilbeGuard contains milbemycin oxime, a powerful broad-spectrum parasiticide, that disrupts the nerve transmission within the parasite, leading to the death of the parasite. MilbeGuard is a once-a-month flavored tablet for dogs, puppies, cats, and kittens, available in four sizes in color-coded packages
