Itch relief magic in a bottle

This product is the cat's meow... or should I say, dog's bark? It works fast, which means my four-legged buddy didn't have to suffer any longer than necessary. My dog stopped scratching his hot spot in no time. It felt like magic, the way he went from restless to relaxed. This is a must-have for all pet parents out there!

A must-have for pet owners

I've been a fan of this product for a while now. The spray format is so easy to use and just what a busy pet parent like me needs. It's really helped mine with their itching, which has meant more play and a lot less scratching. And it works so fast, it's been a game-changer in our household. Plus, you can use it for both dogs and cats. Can't recommend this enough.

Relief for our furry friends

The main reason I like this product is how easy it is to use as a spray. It calmed my pet's itching really quickly. I also like that it can be used for both dogs and cats. My dog got a scratch on her eyebrow from one of our cats, but this product worked like a charm to help her heal! Super convenient, and it actually works.

Stops itching instantly

We have repurchased this many times now, for our own itchy-prone pitbull, as well as for several friends and neighbors' pets. Before finding the PetArmour Spray, we tried other brands, and I was put off by heavy fragrances, or lack of relief for the itchiness. This hydrocortisone spray is the best we have found. It provides instant cessation of the itching without stickiness. There is a mild scent, but it dissipates quickly. The price point is excellent. We have tried this on both dogs and cats with great results. Highly recommended.

Great value for product that does exactly as it says

My senior cat had some issues from the cold dry air of winter (and we heat with wood) and flea reactions. It was very dry and itchy. I used this spray on the affected areas a few times a day for about 2 weeks and it cleared right up and his stopped scratching. I use it occasionally when it gets (still winter) and it keeps his skin clear and moisturized. He's much happier now. Not a terribly strong smell and it goes away after a little bit and didn't seem to bother my Brutis at all.

It provided quick relief from itching and irritation, and I noticed a significant decrease in his scratching within just a couple of days.The spray is easy to apply and doesn’t upset my cat, which is a huge plus. It also dries quickly and doesn’t leave any greasy residue. I feel more confident knowing it’s safe for both dogs and cats.Overall, a great product that really helps soothe my pet’s irritated skin. Highly recommend for any pet dealing with itchiness or minor skin irritations!

Effective Itch Relief with Room for Improvement

This is going to be a positive review because the product indeed works. It's effective, easy to use and provides quick itch relief for both dogs and cats. Plus, it's non-greasy which is a bonus. However, it isn't perfect - the formula could be stronger and gentler on skin. The price is a little steep for the size - a larger bottle or better value would be appreciated. A more pleasant scent and more natural ingredients would also make it more appealing. Despite these, it's a good product overall.
