it only takes one mosquito to give your dog heartworm disease. Heartguard plus is a good prevention medication and i'd give it every month. I give my dog Interceptor every month all year round. its cheaper to do it this way with small dogs because if you only did it seasonally you'd have to do a heartworm test in the spring before you put the dog back on it. Heartworms are something you do not want your dog getting. Its very expensive to treat and can be fatal. Much easier to prevent something then it is to cure it.
