The sentence "我很对不起你的狗的情况" (Wǒ hěn duìbùqǐ nǐ de gǒu de qíngkuàng) is a mixture of Chinese and English and is not grammatically correct in either language. If you would like to offer condolences in Mandarin Chinese, a more appropriate way to express your sympathy would be: "我对你的狗的离世感到非常遗憾" (Wǒ duì nǐ de gǒu de líshì gǎndào fēicháng yíhàn), which translates to "I feel very sorry for the passing of your dog." This conveys your condolences in a more sincere and culturally appropriate manner.
