Pet owners using these products should: Read the label carefully before use, and follow the directions exactly. Labels of all flea and tick products outline their proper use. Use flea and tick control products only on the animal specified on the product's label--dog products for dogs, and cat products for cats. Use only the amount indicated for the age and weight of the animal being treated to prevent overdosing in small animals. Pet owners concerned about the use of flea and tick products should discuss the situation with a veterinarian or a product's manufacturer. A video on the safe use of flea and tick treatment is available on Health Canada's website.
