prepositions

Which prepositions should I use here?
Isabelle was the only one who was reluctant to join in. She came over _______ me and pressed herself ________ my side, looking apprehensive whenever the dog gambolled ________ us. ‘I think the dog should go back to its owner now,’ she said, when he rushed particularly close, kicking up sand ________ a sudden change of direction. ‘Mmm,’ I said. ‘I’m not sure who he belongs ________, though. It’s not a dog I recognize from the village.’ I checked my watch. It was quarter ________ four and would be getting dark ________ long. As if to make________ a point, a few fat raindrops started spattering down on us. ‘Time to go back in!’ I called, waving my arms ________ my head. ‘Hugo, Thea!’ They traipsed back _______ us, their cheeks pink, and the dog trotted behind them, tail still wagging. He followed us all the way to the steps leading up to the café, and I glanced around helplessly, wondering what to do with him. There was still nobody around. ‘Can we keep the dog?’ Thea asked hopefully. ‘Mum would go mental,’ Hugo said, rolling his eyes. ‘Yeah, she’ll cry again, I bet,’ Isabelle said. We all looked at the black dog. He was a cross-breed, part-collie and part-retriever _______ a guess, ________ soft fluffy ears, a thick _______ rumpled coat and a plumey tail.
