Hyperactive dogs "Ruin" adoption (funny video)

[Chicagocanine]

Wow that reminds me of two of my foster dogs... One dog I fostered was a Lab mix who was young, active, and would get overexcited when he saw other dogs and start barking (he wanted to play.) Unfortunately the shelter's adoption events of course always had several dogs for adoption, so he would be barking and trying to get to the other dogs to play, and then if someone showed interest in him he would get excited and start jumping on them.
The most recent dog I fostered was a really cute longhaired GSD, young adult, who would chew on ANYTHING and was very playful. He was a little nippy which I was working on.... However at adoption events where we had to just stand around with nothing to do he would start to get bored and then the nipping and jumping would start... Not a good way to get adopted!
