Sitting for a dog that got a hold of my phone and broke it!?

So I am currently in my first house sitting gig, and I am watching two dogs, one one year old and a puppy. The puppy has been very well behaved and calm except for the accidents which are understandable. On the other hand the one year old, B is his name (not real but to make it easier) has been a handful. He loves to take anything he can and play with it. He takes the pee pee pads and rips them to shreds or anything really. (I was not fully disclosed of this, all I was told was keep doors closed because he will take anything he can to play with she mostly used examples of clothes, was told he will try to take the pads though) and he got a hold of my phone off the table and couch and broke it! Now I did let the owner know and she said she will pay for a replacement phone. I feel bad accepting but it was not my fault and I have taken good care of them and he has not gotten into anything else of hers or mine. Should I accept? Anyone else had this problem?
