DILLON, Mont. -

The Humane Society of Beaverhead County tells us they're packed to the brink, after more than a dozen dogs got ditched at the Rainbow Gathering.

NBC Montana first reported in June how the shelter in Dillon feared they'd fill up after the last Rainbow Gathering in 2000 left them overcrowded.

We checked Tuesday, and Director Susie Brown told us 17 dogs from the Rainbow Gathering are now at the shelter.

She said the shelter is ideally set up for 65 animals, but now they have 87. Brown said they have enough room and food, but things are starting to get cramped.

The shelter is in the process of spaying and neutering those dogs now, and then they'll be ready to adopt.

Brown said they're holding their first ever sale with a reduced adoption fee to find the dogs new homes.
