PetSmart provided the following statement to Team 5 Investigates about the flea and tick products sold in its stores:

"Millions of pets benefit from treatment with flea and tick products each year. We work closely with our suppliers to make sure our products have easy-to-read instructions and appropriate safety warnings.

As we enter flea and tick season, we’ve reminded all of our stores of the potential for adverse reactions to spot-on treatments. We recommend that all pet parents who want to use these products read labels carefully, research what is best for their pet and consult a veterinarian before treating their pet."
