Dog expert's simple free trick stops your pooch 'burning your grass to death'

If you have a dog who loves nothing more than running around your garden, then you might have also noticed that the grass on your lawn isn't always in the best shape. You may have patches of your lawn that have died, which can look unsightly against the rest of your luscious greenery.

And according to one dog expert, it could be your pooch that's ruining your lawn, just by going to the toilet.

Canine guru Dr Sean McCormack explained that dogs have high concentrations of nitrates in their urine, which means they essentially "burn the grass" in your garden every time they step out to pee.
