Asking for a friend (really!). Elderly mid sized dog with a few background health issues (including taking steroids) was dropped off with dog sitter. Let’s call her Paula, is a friend of a friend and has looked after the dog before when he was quite acutely ill a few months ago. Dog managed to get some dark chocolate left at the back of the countertop I believe and now has ended up back at the vet for emergency treatment and overnight monitoring. My friend is obviously very upset and is wondering what is reasonable regarding the payment to the Paula for the dog sitting session (I’m not sure exactly how much this would be) and the vet fees (likely £850+).
