Dog Rocks is urging pet retailers and owners to take part in a 'tear stain' trial in an effort to prove that its unique product can help to solve the problem.

The company has already carried out a survey of 2,000 dog owners, who found that Dog Rocks helped with tear stain.

"The benefits of Dog Rocks on grass are widely known, no more urine burn patches," said CEO Carina Evans. "We now have strong reason to believe that Dog Rocks also alleviates and cures pet tear stain."

If you would like to take part in the trial email info@dogrocks.co.uk or call 01628 822243. You will need to email a picture of your pet suffering from tear stain and include details of breed, diet and habitat.
