I always knew the dog I grew up with laughed. Apparently researchers have now defined what dog laughter is - an breathy exhalation while they are playing. Researchers have shown that it can help calm tense dogs. I have been watching Dog Town on netflix. The episode about saving Micheal Vick's dogs showed them using a recording of dog laughter to help a dog through some stressful situations. I am posting about it here because I know several of y'all have dogs that are high strung and/or have other challenges. This might be a tool tha could help. Here is the website about laughing dogs - http://www.petalk.org/LaughingDog.html . They sell a 45min cd of dog laughter for about $25 shipped - and proceeds go to the animal shelters in Spokane. Just like with gfgkids, it helps to know about possible tools to help them cope, in my opinion.
