I, as a sort-of-Christian, have always found the idea of putting up (and praying to) Mary and various Saints etc, as being rather against the true teachings of God. In that sense I agree with the Islamic teaching - there is no need to be putting up images of anyone or anything. At least not for religious purposes.

But I do live in an apartment with walls covered in art, including images of real and imaginary people. I just don't pray to them.

But back to dogs...

In any country, whether it likes or accepts or tolerates dogs, letting a dog run of lead in a public space is never cool.
