Questions and answers

When does Hartz go on sale?
Hartz discounts cluster around spring and summer flea season and again in early fall. Big-box and drugstore chains also run it in weekly circulars. Check the price history here to see whether a current price is above or below its usual level.
Where is Hartz cheapest?
It varies by product and week. Warehouse clubs and large pet chains usually undercut grocery stores on multi-dose packs, while drugstores discount single packs. Compare the live prices across stores on each product page.
What is Hartz best known for?
Flea and tick control. UltraGuard Dual Action topical kills fleas and ticks and also kills flea eggs, which breaks the life cycle. The brand also sells shampoos, collars, and small-animal supplies.
How do I pick the right UltraGuard dose for my dog?
Match the dose to your dog's weight band: 15-30 lbs for medium and 31-60 lbs for large. Do not split or combine doses across bands. If your dog is near a boundary, ask your vet which band to use.
What is Hartz's return policy?
Returns follow the policy of the store you bought from, not Hartz. Unopened product is generally returnable within the store's window. For a reaction or product problem, contact Hartz directly.
Are there Hartz discount codes?
Deal.ai doesn't list Hartz discount codes. It checks what Hartz products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
