Nathan and I noticed a small, light coloured patch on Truffles' lip last week. Naturally, being hypochondriac dog owners, we took her to the vet.
Vet: It's definitely not a tumour...It looks more like a cigarette burn.
(Seriously, did the vet just accuse me of torturing our dog?)
Me (defensively): That's impossible. We don't smoke. And she lives inside the apartment.
