If using Hartz Nature's Shield flea and tick, how much time before I can start Bravecto?

What are a complete list of the ingredients of this product? I only see “made with” listed but not a complete list. I even went to the Hartz website and couldn’t find the ingredients label. Anyone?
Answer by ChewyFeb 26, 2021
Hartz Topical Flea & Tick Spray for Dogs has the following ingredients: Lemon Grass Oil 0.20%, Cedarwood Oil 0.80% , Sodium Lauryl Sulfate 2.10%, Other Ingredients (Water, Isopropyl, Polyglyceryl Oleate, Glycerin and Vitamin E) 96.90%.

Does this need to be reapplied throughout the day to be effective? It’s not a time limit of effectiveness.
Answer by ChewyJul 29, 2022
This product should be applied weekly as needed.

is this product water proof?
Answer by ChewyJul 18, 2022
If you choose to bathe your pet before applying this spray, wait 48 hours after bathing to apply. If you choose to apply the drops first, then it’s best to wait 48 hours after application to bathe your pet.

Safe & Effective!

This stuff works wonders and it’s plant based!!! I got to try the Hartz Nature’s Shield Flea & Tick Dog Spray for free thanks to Hartz and it has worked better than any of the other flea sprays we have tried in the past. It repels mosquitoes and kills fleas, flea eggs, flea larvae, and ticks. The best part is that it’s free of parabens, dyes, and harsh chemicals, so I know it won’t harm my pets and it’s safe for my dogs, my family, and my home. Since using it, I haven’t noticed any fleas and the only tick I’ve found came in on me rather than the dogs. It seems to really be working well. The dogs aren’t a fan of being sprayed but the benefits it causes outweigh the angry pups (we also use a dog perfume spray after their baths so they’re used to being sprayed down). I think it’s much easier to use than topical drops and it won’t fall off like a flea collar may. It also conditions their coats with vitamin e. I really like the scent as well (with cedarwood and lemongrass oils). I highly recommend it to other dog parents. I received this product free in exchange for a review but opinions are 100% my own.

Extremely Recommend

I received this as a product to test from Hartz. The simple understandable directions for use were really nice. (Most products over do the directions with big unnecessary words or have a complete lack of directions on the products.) The container the product was bottled in was easy to manage and use. My dogs weren't phased or startled by the spray action or application. Product smells nice which was surprising but appreciated. Product brushed into fur no problem. Didn't make the fur hard or oily. My pups fur was actually quite soft and smelled so good for quite a while. The product didn't have any negative affects physically or medically. No itching, no hair loss and no behavior change. I am extremely pleased and highly highly recommend this product. If your pups sleep on the furniture or in your bed I suggest this product. Especially if you have kids that are activly interacting with your pups or if the pups are sleeping in your kids bed/room. It's completely safe for your pet and your child. Best product I've ever received to test and the best flea and tick product I have used in my pets yet! Highly recommend!!!

Keeps Fleas Away

When I first moved to Central Florida my dogs were unexpectedly infested with fleas. We live in a wooded area and didn't realize how bad it could be. Since then we've learned we have to regularly keep up with prevention. My dog's take Flea medicine to help prevent but I have never trusted the flea sprays because they are often to harsh to have around children. With that being said, I was very excited when Hartz sent me this natural Flea and Tick Spray to try. It isn't made with all the harsh chemicals and it's completely safe to have around children. I think the smell is pleasant as well. I've been using this when my dogs have time outdoors to prevent any fleas jumping on them and keep the mosquitoes away. It works really well and I would definitely recommend it.

It works but I have a couple of issues with it.

I use this on my outside dog and it seems to have helped with ticks and fleas. Also it instantly got all mosquitoes to leave him alone. That being said I have a couple of issues with it. I don't really like the fact that sodium lauryl sulfate is the number 1 active ingredient in it as it says there isn't any harsh chemicals in it. My other issue with it is that it says on the front of the bottle "safe to use arround children, pets & home". Then in the back of the bottle it says "if on skin: wash with soap and water". So I'm confused if it's safe to use around children why does it say you need to wash with soap and water if it gets on your skin??

Works Well

Fleas love my mom’s dog Dexter. We live in a semi-tropical environment so flea season is all year round. I like to be preventative and use either a pill or a spray so I tried Hartz Nature’s Shield Flea & Tick Dog Spray on Dexter. As the directions read you spray a light mist all over the dog avoiding their face. The mist is a tolerable lemonly scent which Dexter didn’t seem to mind. It’s been over a week since spraying Dexter and so far so good, no fleas . I will wait a couple weeks for the next dose . Meanwhile, Dexter is a happy boy.

Great & Safe product

During the Summer our favorite place to go is always the river where the ticks are plenty! My dog is now a senior and sensitive to smells. Since using this we have been to the river three times and normally I would have anywhere between 2 to 10 ticks on her and I would get them off. Since using this we have not had any ticks to worry about and although fleas have thankfully not been a huge issue, I have full trust that they won’t be either. I have full trust in this brand and full trust in this product

Works Wonders

I thought this would be a good to have in the summer since in the south the flea get bad, my animals are on a flea medication. However i will spot one or two on them. I was impressed how much this product worked and I am happy because it is as all natural and not toxic to any of my pets. Before buying this spray ,they would scratch continuously. But after applying it thoroughly, they no longer continue to scratch and scratch. I also use it on my dogs bed. I know it works, as I found 2 dead fleas on his bed. Also my pets sleep on my bed with me too ,I spray my entire bedding, and it doesn't leave a harsh after effect scent. I sprayed the couch, carpet and as well as both dogs The scent is pleasant. I can say it does not feel greasy in my pets fur.

Works Great

Due to our weather this winter and spring, Flea and ticks have been predicted to be high. We've never had an issue with either before. Just because it has never been an issue doesn't mean it can't quickly become one. We thought it would be a good idea to use the Hartz Nature's Shield Flea & Tick spray as a preventative measure. It seems to be working well. The scent of cedarwood and lemongrass was actually more refreshing than normal sprays of this nature. It did not stain anything. Plus, I really liked that the formula was free of parabens, harsh chemicals and dyes. Afterwards, our pug mean mugged us for a bit. It was our only downside.

Amazing product

My dog hates being bathed so flea and tick shampoo usually ends up everywhere. This spray was a quick effective way to coat her fur for flea and tick prevention. It comes out in a fine mist spray and very evenly. It's plant based and safe for children and pets which is extremely important. It's made with cedarwood and lemongrass oils so the smell is almost a light uplifting fragrance. It's provided long lasting treatment of fleas and ticks for my fur baby. I've noticed less itching and no signs of fleas or eggs and no irritation.

Works for us!

Product was gifted to me- I live in a pretty rural area so fleas and ticks are a concern for our pups. I have really loved using this spray. I love that it a more natural approach and very easy to use. My dogs don't like being sprayed initially but it hasn't caused any irritation and the smell is nice
