The delighted dog wags her tail and whines with joy during the emotional reunion.

The video has been viewed more than one million times since it appeared online last month.

One user commented: 'I think this is probably the closest thing to crying (tears of joy) that I've ever seen from a dog. God Bless your family and sweet Bugaboo. Thanks for serving for our country!'
