Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

How long after applying can I wash my dog
Answer by ChewyAug 12, 2022
This product remains effective when treated animals are immersed in water (e.g. swimming, bathing). Water immersion repeated weekly for one month and starting 48 hours after treatment, as well as shampooing 2 weeks after treatment do not affect the efficacy of this product. However, in case of frequent shampooing, or bathing within 48 hours after treatment, the duration of activity may be reduced.

If it’s raining and I applied it at 5pm the day before is it already dried and water proof? At 6-7am the next morning?
Answer by ChewyDec 04, 2019
Yes. This waterproof solution dries quickly.

My dog used to be 20 lbs, now he’s up to 25 lbs.Both of us have gained weight during this pandemic :( Will this be effective on him? I have 4 treatments left.Can I use 2 treatments on him at once since he’s over the weight?I don’t want to waste it but will if it’s not effective or safe for him.
Answer by ChewyJul 12, 2020
This treatment is made for dogs 11-20 pounds. For dogs over 20 pounds we recommend the Vectra 3D Flea & Tick Treatment for Medium Dogs.

Do i need a script from the vet for this
Answer by ChewyApr 30, 2020
This flea and tick treatment does not require a prescription from your veterinarian.

Waste of money

We bought this for our 20 lb dog and 15 days after applying it he had hundreds of fleas. What a mess! He had never had fleas before. He is 6 years old. We are going bock to our old brand.

My dogs have a reaction to this medication

Since I applied this to my dogs as directed they have been scratching nonstop, I would like to find a different Flea & Tick Solution this is just not working out for our dogs Owen is a Cavalier king charles, same with Vivien she has also been scratching nonstop, I have applied this to all 5 dogs and there is only 1 our of the 5 that it doesn't seem to bother. I need to find a different brand, just because it doesn't work for mine doesn't mean it wont on other's.

Effective flea preventive

Been using this flea preventive in the 21-55 lb size for 7 years. Seems to work as no fleas in that time. (Knock on wood), with no side effects to dog. Dries quickly and slightly oily residue dissipates in 2-3 days. We have a short haired dog.

Disappointed

So after reading ALL the reviews for various brands, I had such high hopes for this because the others said they didn’t work or when they did they were inconsistent. Needless to say, my poor dogs are covered in fleas, they’re strictly indoor but go out to handle dog business, regardless, we have major issue now. My dogs also infested my indoor cats now. Cue Vectra 3G. Dogs got bath, blow dry and clipped hair a little so I applied in thin line from tail to shoulders, as explained, first couple days we were perfect. ZERO FLEAS!! No more biting, chewing, pacing around from anxiety from being bit. Well it’s been 12 days since I applied the topical treatment to my girls and this morning drinking coffee, I’m accompanied by this…. My poor dogs are full of fleas yet again. OH side note: we did treat entire yard to try to help situation and still

Packaging change

The packaging has changed from the teal to the purple. It is still the same product but the manufacture has changed the packaging color to purple on all of the different boxes. All weight classes boxes are purple. Still the same great product!

Keeps those ticks off!

My girl was on Vectra 3D because it has a hot-foot effect for mosquitos and ticks, and we live in an area with both. She came up north with heartworm (and larvae in her blood) so we had to be super careful. I'm keeping her on this -- I'm happy with the tick-prevention and rarely find a tick on her by the time we get home and I look her over. Does that correlate to Vectra 3D or some other reason? I don't know, but this is working for us. She is a short-hair black lab/terrier mix. ORDER FROM CHEWY so you know it's the real deal and not very old product. If you order from elsewhere, you don't know the source the vendor used. Ordering from your vet is 1.5-2X the price. I find this easy to use if you follow the directions. I wear gloves and "dot it" up her spine in short lines, which makes it easier to know the product is going all the way up tail to shoulders. I take my time to get it close to her skin and rarely see an oily line up her back. I use it before bed and then in the morning give her a quick brushing down her back if any residue is left or the "previously wet line" is still there.
