Why should humans be the only ones who get to wear football jerseys in support of their favorite team on game day? Now, pet owners can buy matching football jerseys for their dogs, so their companions can watch the game from their side of the recliner, in style. Football jerseys are available for dogs in almost any size and style, for any team in the NFL, or even college football. Jerseys come with long sleeves or short sleeves, with either the city or team name and a player number decorating the side facing the dog s back.
