The Ontario SPCA says, "As many pet owners know, the spring marks the time for annual vaccinations, veterinary check-ups and reviewing your pet’s heartworm and flea/tick prevention program. We know that heartworm prevention is critical to your pet’s health, but many owners don’t fully understand what it is, why it is dangerous and how to prevent it. The AVMA recognizes April as National Heartworm Month to help raise awareness about heartworm.
