PHOENIX (KSAZ) - Maricopa County Animal Care and Control is experiencing major over-crowding in both the west and east shelters.
Jose Miguel Santiago, the Public Information Officer for MCACC, says the west shelter needs at least 200 dogs to be saved, and the east shelter needs 100 large dogs to be saved.
On a Facebook video, Santiago said there were only 14 open kennels as of Thursday.
Because of this adoption crisis, Arizona Animal Rescue Mission have given MCACC $5,000 to help adopt out the 300 dogs for free.
The free adoptions started on Thursday and they plan to finish on Sunday, April 15.
The free adoption will only apply to older, large dogs that weigh 20 pounds or more.
MCACC says they only have a few kennel spaces open, and if the dogs do not get adopted out, that the shelter will have to "make decisions we simply do not want to make."
These free adoptions do not apply to small dogs, puppies or shelter super heroes.
