I had something similar with a work colleague
She asked if I'd have her dog for 10 days and I love dogs (and knew this one well) I agreed as I love dogs but can't have one myself
She sent him with a knackered harness,chewed on lead,a bag of human sweets/cakes,a bottle of crusha milkshake mix and a much loved toy
No tins of food,no poo bags or biscuits for him so I ended up at tesco,buying him tins of food,which cost me about £20 and thankfully ds had left his dogs lead and poo bags from when we last had his dog (he was fine with us using them)
We fed the dog,walked him for hours each day,played games with him and picked up the sloppy shits (and the shits where like water)
Sent him back once she came back-she seemed to be grateful,snatched him from dp and walked away and that was the end of that-didn't ask for the money for his food,as I was just happy to help (and didn't get a thank you,let alone a bottle of wine or some chocs)
Or so I thought-she went round at work,telling everyone we'd abused him by not feeding him the food she'd sent (cheap sweets and cakes-which we sent back with him),we hadn't bought him his 3/4 Maccies milkshakes per day (£7/8 a day-chocolate is his fave apparently-shes in debt up to her eyeballs and cant understand why)we hadnt given him his crusha shakes (she wasnt offering money for the endless bottles of milk-im not even sure if dogs can have milk) he seemed happy enough with water,we'd not bought him a new harness and lead from the local,posh and very expensive pet shop and walked him too far (he's a staffie so needs more than a trip round the block)
we had taken him to places she wouldn't have dreamed of for lovely walks and he seemed to enjoy himself
I was fuming-wed really worked hard to make him happy and well looked after,but didn't say a word to her as she was leaving and I was that angry,i would have slapped her
Thankfully all my colleagues stood by me as she was known to be a cf and lots didn't agree with how she fed or treated him (she's not abusive but her bar is very low)
Didn't hear a thing once she'd left work-until a year later-she popped back up and wanted us to have him again for the same week
I'm afraid I took great pleasure in saying 'no,our care wasnt good enough for him last time we had him'
Never heard a thing back from her
I'd be telling this woman she owes you for the dog care (my one regret is I didnt) minus the price of the posh dog food
