Mike always leads? A dog's life? Since his divorce.

Mike has been living a hard life since his divorce.

His? Father's? Bankruptcy led？ Him? Answer? Dog's? Life. ?

His father's bankruptcy made him lead a hard life.

For example:

The dog days in summer are the hottest days of the year.

These? Is it? That? Dogs? Day; ? Watermelon? Is it? Just? Are you online? Season. ?

Love me, love me, love my dog, which means "warning someone that if he wants to have sex with you, he must be willing to accept everything from you", that is, "love me, love my dog".

In the past, keeping pets was not as unusual as it is now. At that time, many pet owners didn't like keeping dogs, so it was not unusual to keep dogs at that time. So later people extended this idiom to the present meaning. However, this idiom is not popular because many people like dogs now.

Examples are as follows:

Love me, love my dog. If you love anyone, you will like everything that belongs to him.

Love me, love my dog, it depends on my master.
