We used Hartz flea and tick topical treatment for dogs (5-14lb dogs) for years with our other dog Mac and now use it on our new dog Sonny as well. Works incredibly well. Thankfully, Sonny hasn't had any ticks to date but when it was used on Mac, we easily removed 2 dead ticks. 3 tubes come in a pack. Couldn't be easier to use. Use the cap to pierce the tube open. Starting from between the dog's shoulder blades, dispense the product along the dog's back. That's it. Done. Lasts 30 days. The dog can be bathed/groomed after the product has been dispensed. There is a bit of a scent that lasts a few days before fading. We live in an area surrounded by woods and mountains so its imperative our dogs are well protected against ticks/deer ticks. (This also kills fleas, flea eggs and prevents reinfestation for 30 days) I am very pleased with how easy this is to use and especially pleased with the results. The incredibly low price makes me happy as well. lol. We use this year round and are signed up for Amazon's 'subscribe and save' so I don't have to worry about remembering to purchase it in the store.

Used for 2 months so far and it seems to be working great. My only complaint is that it takes a long time to dry. The stuff I have used in the past that was similar dried much faster. But other it's good. I will buy it again. Just have to plan ahead a little. Adding on to this with my 3rd order. My dog has been flea and tic free through an entire summer, using just this product.

I have two miniature toy chihuahuas 5lbs and 8lbs And they still had fleas cralling on them after the dose. I strongly Don't recommend Heartz At All

I gave this a low rating because it didn’t seem to work on my dog. She has been itching still even though I applied the drops. I have done it before so I know how to apply it. I part the fur and put it from the back of the neck between her “shoulder” bones all the way to the tail while making sure it gets to her skin. I’ve given it some time before reviewing so I can see if she still had the fleas and she still does. I’m trying diatomaceous earth now. I hear it’s a good natural way to kill the fleas along with many other pests/insects. Hope it works better than these drops. I guess you get what you pay for in this case. Cheap but didn’t work for my baby.
