goodbye dog

Question
Now, here's a question you probably don't
get asked often....

What kind of (household?) product can I put at
the base of the tree out front that will keep
this dog from doing his daily am duty on it?
The grass around the tree is a nasty yellow
and not geting better. What will make that
dog run to some other tree on the block?(!) Can't
put something that will harm the dog or the
tree...but there must be something that dogs
just hate the smell of. Can u help? Thanks --Max

Answer
There are two things, cayenne pepper may work, so you should try it; if cayenne pepper doesn't work, you can buy a dog repellent from any pet shop. There is one problem however, some dog repellents don't work or actually will make the dog want to do it in that area that it has been sprayed.
Good luck...
