I've never tried taking dog pictures before, but when I asked this lady's owner if she objected to photos, he said she loved them. (The other week I encountered a dog which wouldn't walk past me to reach its owner and was informed that it was because the dog hated cameras! And I wasn't even attempting to/intending to snap it)
