My friends dog, who i looked after from time to time, had surgery to remove a cancerous lump. I wanted to send her a card and loved that she could eat it. The only feedback I would give is that I bought this for a friend's dog and not my own, to be able to say its going straight to the recipient would be better than pretending to be the dogs owner. The edible ink was an exciting idea but found I'd be buying the pen and with it being sent straight to the dogs house i couldn't write my own message on there, another thing that would've been great to do.
