Then she turned to her sons and said: ‘But this is not enough, my sons, I must have another proof as to what sort of wives you have chosen. In the house there are three puppies. Each of you take one, and give it to the woman whom you mean to bring home as your wife. She must train it and bring it up. Whichever dog turns out the best, its mistress will be my favourite daughter-in-law.’ So the young men set out on their different ways, each taking a puppy with him. The youngest, not knowing where to go, returned to the pond, sat down once more on the bank, and began to weep. Flop! and close beside him, he saw the frog. ‘Why are you weeping?’ she said. Then he told her his difficulty, and that he did not know to whom he should take the puppy. ‘Give it to me,’ she said, ‘and I will bring it up for you.’ And, seeing that the youth hesitated, she took the little creature out of his arms, and disappeared with it into the pond. The weeks and months passed, till one day the mother said she would like to see how the dogs had been trained by her future daughters-in-law. The two eldest sons departed, and returned shortly, leading with them two great mastiffs, who growled so fiercely, and looked so savage, that the mere sight of them made the mother tremble with fear. The youngest son, as was his custom, went to the pond, and called on the frog to come to his rescue. In a minute she was at his side, bringing with her the most lovely little dog, which she put into his arms. It sat up and begged with its paws, and went through the prettiest tricks, and was almost human in the way it understood and did what it was told. In high spirits the youth carried it off to his mother. As soon as she saw it, she exclaimed: ‘This is the most beautiful little dog I have ever seen. You are indeed fortunate, my son; you have won a pearl of a wife.’ Then, turning to the others, she said: ‘Here are three shirts; take them to your chosen wives. Whoever sews the best will be my favourite daughter-in-law.’ So the young men set out once more; and again, this time, the work of the frog was much the best and the neatest. This time the mother said: ‘Now that I am content with the tests I gave, I want you to go and fetch home your brides, and I will prepare the wedding-feast.’ You may imagine what the youngest brother felt on hearing these words. Whence was he to fetch a bride? Would the frog be able to help him in this new difficulty? With bowed head, and feeling very sad, he sat down on the edge of the pond. Flop! and once more the faithful frog was beside him. ‘What is troubling you so much?’ she asked him, and then the youth told her everything. ‘Will you take me for a wife?’ she asked. ‘What should I do with you as a wife,’ he replied, wondering at her strange proposal. ‘Once more, will you have me or will you not?’ she said. ‘I will neither have you, nor will I refuse you,’ said he.
