Great Protection for My Pup! 🐶🛡️
I’m really happy with Hartz UltraGuard! It works fast to keep fleas and ticks away, and it’s super easy to apply. Knowing my dog is protected from pesky bugs gives me peace of mind. The monthly treatment lasts long, and it’s affordable too. Definitely a reliable choice to keep my furry friend safe and comfortable! 🐾💖

Good value for money
These flea treatments give you the value for your money, relief for you pet, and leave you worry free knowing this is a reliable brand. I took a dog in and gave her this treatment and it gave me no issues whatsoever. She is prone to dry skin but this did not affect her. also considering she was outside most of the time I’d say this is a decent product considering it has lasted the full month. If you are looking for a affordable flea treatment try this one.

Effective treatment.
We have been using this for a while now on our house dog. We appreciate that it prevents fleas and ticks as we have not found a single flea on him in the year since we started using it.

The 50/50 split
So it looks like this treatment only works with a certain type of chemistry within your dog and then it doesnt work at all for others. That is my hypothesis because I cant imagine the half that left a positive review were all lying in these reviews. For my girl I bought the largest size they have and it goes for up to twice her weight so i shook it good and only put half on her since it has such a high weight allowance. Well first off it wanted to sit on top of her skin it wouldn’t absorb into her. It sat there on her like this for over an hour until it was nearly bed time and she sleeps in our bed so I wasnt having that in my bed even if she does stay at my feet. So I ended up having to try to smear it into her fur with a paper towel. Then I noticed this is more of a repellent than it is a killer. So keep that in mind. You’ll want to have your pet outside when you apply this if you think they could possibly have gotten a flea or 2 because if so then they’re going to jump off your dog inside your house and who wants that? Then you’d need to treat the whole house with borax. Which I don’t do bugs at all ever so the minute I saw 1 flea jump off of her from this mess I ran to the store for borax automatically. Anyways moving on then I noticed a flea that wasnt jumping off he didnt seem bothered by it as the one was that did jump off. Lol so apparently that 50/50 split I mentioned at the start of my review fits perfectly as my ending too. I noticed this only repelled about half the fleas so yeah it must come down to each fleas certain type of internal chemistry as to whether or not this works. 🤣 full circle
Haven’t tried it yet have just got them I had one down about hour –
Got to give this and stuff like this time
I’m not sure it even works because I used them but the flease still there. Not as many but still populating it has a strong enough smell to your pet knows that you putting it on them I don’t know how effective it is like I said there been no skin problem but there enough in the pack to put on your animal while maybe after get it on them for while it might work
