 If you're extending your holiday celebration into the weekend with a camping trip or visit to the lakes, animal experts are asking you to think twice before taking your dog with you. First of all, they say you should be careful with the foods you give your dog. Many of the foods at barbecues can actually be harmful to your furry friends. And while your dog might be used to camping and boating with you during a normal weekend, Fourth of July weekend brings a higher risk of injury or chance of them going missing.
