Sulphur Powder and Urine stains
As you walk around Barcelona you may have noticed the yellow powder that is sprinkled outside some shops or buildings. This yellow powder is Sulphur and is supposed to repel dogs from peeing in that particular spot.
In Malaga according to Sur.es, the Ayuntamiento have imposed a fine of between 75 and 500 euros if shops or residences sprinkle it outside their buildings. This new law comes into effect this month - April 2017.
At the moment there seems to be no definite evidence that Sulphur is effective in repelling dogs from peeing in certain areas. I cannot comment on whether this tactic works or not, but I do think that the sulphur makes the outside of buildings look very ugly!
Sulphur can harm your dog if ingested in large quantities, inhaled in large quatities, or if the dog's skin is exposed to it directly.
In my travels around Barcelona i have not heard of any dog being affected by the sulphur powder. It is not tasty enough!
Sulphur is a product used in horticulture to prevent plants from insect damage.
Wouldn't Sulphur cause more irritation to humans if picked up by the wind and inhaled?
Once a dog has urinated in one spot, the urine acts as a 'peemail' to other dogs, informing them of their breeding status, health and a wealth of other very useful information. These spots then attract other dogs who also want to broadcast their status.
If a dog has weed indoors then they will return to the same spot to reinforce the message that the previous smell already contains.
Do we use bleach to clean up urine stains?
Animal urine contains ammonia amongst other ingredients.
Bleach contains an ingredient that reacts with the ammonia in the urine breaking up the molecules and creating toxic gases, but, in the process this chemical reaction also strengthens the smell of the stained spot which broadcasts a stronger and more insistent message to other dogs, to come and wee in the same spot.
The same thing happens if the dog urinates indoors. It will return to the same spot to reinforce any diluting messages.
What is the best way to clean up urine stains?
Here are some suggestions
For cleaning the outside of buildings, a mixture of vinegar and water in a bucket with a good brush will suffice.
