A dog doesn't care if you're rich or poor, educated or illiterate, clever or dull. Give him your heart and he will give you his.

Never slow down, never look back, live each day with adolescent verve and spunk and curiosity and playfulness. If you think you’re still a young pup, then maybe you are, no matter what the calendar says.

In a dog's life, some plaster would fall, some cushions would open, some rugs would shred. Like any relationship, this one had its costs. They were costs we came to accept and balance against the joy and amusement and protection and companionship he gave us.

A dog is the greatest gift a parent can give a child. OK, a good education, then a dog.

Such short little lives our pets have to spend with us, and they spend most of it waiting for us to come home each day. It is amazing how much love and laughter they bring into our lives and even how much closer we become with each other because of them.

When I wrote 'Marley & Me,' I had a clear audience in mind. And it did not include children. I wrote my book for adults and assumed only adults, and possibly teenagers, would be drawn to it.

Only then did I see. Something was amiss with Patrick's snap-on one piece, or "onesie" as we manly dads like to call it. His chubby thighs, I now realized, were squeezed into the armholes, which were so tight they must have been cutting off his circulation. The collared neck hung between his legs like an udder. Up top, Patrick's head stuck out through the unsnapped crotch, and his arms were lost somewhere in the billowing pant legs. It was quite a look.
