How does it work?

Peterals is an all-natural solution to grass burn patches created by your dog’s urine, as
well as a lawn repair aid. Simply add the minerals/rocks to your dog’s main water
source. Once done, the burn patches should visibly diminish or stop appearing within
4-6 weeks of using Peterals.

  • 1 Begin by washing the minerals under cold water to remove any residual dust or dirt.
  • 2 Place the minerals into a suitably sized jug, you need to use 100g of Peterals to every litre of water.
  • 3 Ensure that the minerals are fully submerged and then leave the jug to sit for 10 hours. During this period, the minerals will purify the water by removing the nitrates that cause the burn patches on your lawn.
  • 4 After 10 hours the water is ready for your dog to drink. Just pour it directly into your dog’s bowl!
  • 5 Leave the minerals in the jug and fill it with the appropriate amount of fresh water straight away. Then, leave the jug to sit for another 10 hours, this will ensure you have another fresh batch of purified water at the ready. If you do this once in the morning and once in the evening you’ll have two batches of fresh water each day.
  • 6 That’s it! You can repeat this process as many times as you like for up to 2 months. After 2 months, it’s important you replace Peterals with a new batch.

Here’s what our customers have to say…

"Bloody great. I have 5 dogs two are bitches. No more yellow patches. I have a lidded bucket marked to 6 litres added the stones let it sit overnight and then pour into the water bucket. We also have a water fountain in the garden that the dogs drink out of so we started to op out the excess into this as well. Seriously it really does work used properly."
