I've been looking after a friend's dog while they have been on holiday. On the bank holiday the dog got into a bag that had some snacks in it and ate a load of raisins (raisins can be super toxic to dogs). The bag was on my kitchen work top, and has been there for months, my two dogs have never bothered with it and I actually thought it just had my shopping bags in it. I took the dog to the vet for treatment (along with my littlest dog who also ate some of the raisins once they were on the floor open) and the cost was insane because it was a bank holiday and out of hours. My insurance covered all bar my deductible of £60 for my dog, and I put the other dog's bill on my credit card. I was in touch with the other dog's owner and we said we would sort it all out when we got back. Here's the problem - my friends do not have insurance on their dog anymore (I know I should have checked before letting him through the door, but I am apparently very naive and assumed responsible, and reasonably well off, people have pet insurance). I said I would cover the amount that would have been a deductible, but as it was their choice not to insure the dog they would need to cover the rest as I simply can't afford to. They got really stroppy and said they wouldn't have taken the dog to the vet because he eats stuff all the time and they aren't paying the bill. Raisins can be super poisonous, and the amount the dogs had eaten was a potentially fatal quantity. They did give me some money as I'd saved them a fortune in kennel fees, but it was less than 1/4 of the £400 vet bill (and a token amount when kennel fees are £40 a day and I'd had the dog a week.) I know I should have been more careful about checking there wasn't food in reach of the dog, but I don't believe I should be left struggling for the next few months when I was doing someone a favour in good faith and their dog pulled down and destroyed a bag to get to something my own dogs hadn't even looked at for the (at least 3) months it had been there. So AITA for asking them to cover the bill over and above the amount of a reasonable insurance deductible?
