I love the service. All coordination happens with Nikki (the lady who runs Bark On) over WhatsApp; she sends the menu, you pick what you want, and voila, it gets delivered to your doorstep.
I ordered Bark On's peanut butter cake in a bone shape both times (they've got a few flavours and shapes to choose from).
I've also eaten the cake myself, so can vouch for it being human-friendly. π
