Questions & Answers

5 Customer Questions

Are these safe for puppies?
Answer by ChewyAug 17, 2022
Use of these rocks is safe for dogs of all ages and it is safe for all pets who may share the same water bowl.

How many rocks come in a bag? And how many rocks go into one bowl?
Answer by ChewySep 01, 2022
As the rocks vary in shape and weight, the amount of rocks will vary. The full 200 gram package should be placed into the water bowl. For best results replace your dog's drinking water daily. The Potty Rocks last 2-3 three months and recommend changing every 2-3 months. If you start seeing spots on the lawn prior to that you should change the rocks.

Would this work to prevent damage on wood floors? If so, how long does it take to work?
Answer by ChewyJan 16, 2023
This product is not designed or tested to prevent damage on wood floors. The Potty Rocks are placed directly in your dog’s water bowl. Rocks will filter out some of the impurities that cause your grass to turn brown, like metals and nitrates.

How often do you change the rocks? How long do they last?
Answer by ChewyAug 17, 2022
The Potty Rocks last 2-3 three months and recommend changing every 2-3 months. If you start seeing spots on the lawn prior to that you should change the rocks.

Potty Rocks rock!!

My sweet boy Knox is in end stage Cushings Disease, and let me tell you his urine odor was beyond putrid. After just a week of the potty rocks, it took him a day or 2 to want to drink out of the bowl with the rocks in it (provided one w/o) but it has made all the difference in the world! Truly surprised, amazed and very pleased with these rocks!

These actually work!

I was skeptical but thought what the heck. I’ve waited a couple weeks to do the review and the lawn is recovering, less spots as hoped. We have one of those 2 gallon water stations and we just put them in the jug. Seems to be working!

Using for about a month

Our yard is pretty much covered in brown spots but we have seen an improvement since using the Potty Rocks meaning I haven't noticed new spots. It's especially noticeable around the edges where the boys like to lift their leg to mark. The dogs don't seem to mind that the Rocks are in their bowl almost as if they weren't even there. I use them in the "community" water bowl.

Got the pup and as he grew the acidity in his urine was making our yard a sea of brown spots. Pup has a water bowl upstairs and downstairs - within 40 days it worked 100 percent!

Great for 1 Dog, Not 3 Large Dogs

My family and I recently moved into a home with a smaller home, and noticed lots of yellow spots in our grass. We have 3 large dogs (2 labrador retrievers, and 1 belgian malinois). After using as directed, I started seeing new yellow spots after 3 weeks. So, the rocks have already been "used up", and I'll need to replace them. The packaging doesn't state what 2-3 month longevity is based on... one dog? a whole pack? the size of the dog? how much water the rocks are "good" for? I suggest this needs to be revised, and customers need to consider these factors before purchasing. TL;DR - the rocks work, but if you have multiple dogs, large dogs, or very thirsty dogs, you'll need to change them within 1 month.

No more dead spots

After using for 1-2 weeks, urine was not causing dead spots in the yard.

Works for us

We have a 70 pound Dane/lab mix and her urine was ruining our lawn. Since using these for two months we have green spots instead of yellow ones in our yard!

Potty Rocks have saved our grass!

We had one of those spotted lawns from dog urine until a year ago when we started using Potty Rocks (and another brand). Potty Rocks seem to be a better price point for us, but work just as effectively. The directions instruct pet owner to put the rocks right in the bowl. We have a 2 liter pitcher in which we place the rocks and fill daily, then pour the water into the bowl from there. This method has worked well for us. It took a few weeks to become effective. Be patient!

Hoax Hoax Hoax

I can’t believe as a scientist I fell for these. Don’t work and in reality can’t work. Basalt rock has absorptive properties but it’s the urine that burns and treating water doesn’t work. Paramagnetic is a fancy way of saying I’m selling snake oil

Don’t work , plain and simple. Tried for 2 months, lawn full of yellow spots. Also, price increased.
