70 percent of people sign their pets’ names on greeting cards and 58 percent include pets in family and holiday portraits, according to a survey by the American Animal Hospital Association. That’s no surprise to us — just more evidence of how dogs are part of the family. We’re gathering together an album of canine-inclusive holiday portraits, and featuring them in the slideshow above. Hairstyles and fashions may have changed through the years, but the spirit of joy shines through them all. Share your photos and cards with us and enjoy some seasonal cheer.
