Hello! Can anyone tell me how I can clear up the dead round spots in the lawn which were caused by dog urine? I just moved into a new house and the previous owners had a dog that obviously did a fair bit of damage to the grass.

Thank you - Allan R

We have three dogs and every spring, after the snow melts, we also have those ugly "dead" spots in the grass where they've been urinating all winter.  The spots always "fix" themselves quite quickly, with no reseeding or any other help from us, and the lawn seems no worse for the wear in short order. 

The advice in this forum has been correct.  Generally, dog urine patches, if by a male dog, will come back through the season.  It does sometimes take a while, depending on:

• the size of the dog
• the constancy of the urine that spot, and
• whether the dog has any bladder problems

If it is a female, and she was in estress , then the problem can be more severe and the patches will require some work as suggested by the radio horticulturalist, in order to combat the lower pH due to the acidity in the urine.  This will be required as well for areas where a dog constantly deficates.  The concentration of urine is, like anything else, to much.

i have been told a spoon full of tomato ketchup after each mean to the dog will stop this from happening again
