Sister not looking after my house

[BipolarSunset]

Really need your help here.

So me, DH and DS have just come back from holiday, sister stayed at mine all week to look after our dog.
She works 2 days a week so we had arranged a friend to pop in and take DDog out for a walk and to feed him.

Get a call Wednesday whilst away from friend saying my house has been completely destroyed, DDog was locked in his cage (we never put him in if we go out) which was filled with urine and there was rubbish everywhere.
Friend had cleaned cage, bathed dog and then took him out. There was also a used pregnancy test just sitting on my toilet cistern.

Come back today and house isn't much better, spoken to my mum who has defended my sister saying that friend had invaded her privacy and that DDog was hard to look after and pretty much that I am a neat freak.

Am I being unreasonable?

Have also been sorting out the house and cases since 9am so was quite a bit to do.

The balance has been restored in my house and I'm much more relaxed!

@Foxysoxy10 doubt I'll be getting an apology any time soon, I understand that she was doing me a favour but we were also trusting her with our house for a week. To have some time as a little family of their own and for her FIL to have a needed break as it obviously can't be easy for any of them. The fact DM has gone down on her side isn't any surprise sadly they're both so alike.
I just thought she'd have a little more respect for me being such a 'neat freak' as others have said to at least have my home in a reasonable condition when we arrived back.

Op I think your getting a bit of a hard time because you used the word destroyed when your kitchen is simple untidy.

Now I think most people would be upset to come back from holiday to that mess. I know I would be. So YANBU to be annoyed.

Keeping your dog locked in a cage would really piss me off. You trusted your sister with your home and your dog and she didn't look after either. I can see why you feel angry and let down.

Think it was the friend that used the word destroyed... To describe the entire house, not just the kitchen. The same friend that described the dog situation... So perhaps both were slightly exaggerated.

Hardly destroyed! You sound very hard work

I'm not a naturally tidy person and my own house has a 'lived in' look but if I was house sitting for someone whose house was near as a in, then that's how I'd leave it. I'm with you op. Also, dogs naturally avoid messing a sleeping area (hence why 'crating' is used to speed up house training'
For a house trained dog to pee where it sleeps/has been locked in, would mean it had been left in long enough for the poor dog not to be able to hold on any longer. My dog can go all day without peeing. So she was disrespectful of your home and neglectful. Imo

Was the picture of the house taken by your friend along with the cage? Or what you came home to? How was the rest of the house?
