GILBERT, AZ - MCSO is currently serving a search warrant at the Green Acre pet boarding business after more than 20 dogs were recently found dead.
Air15 video showed a heavy MCSO presence in front of the boarding center near Val Vista and Queen Creek Road in Gilbert on Wednesday morning.
Sheriff Joe Arpaio said deputies found a dog buried in the yard at the facility on Wednesday morning. There is no word if the dog belongs to the owners of the facility or was one of the dogs who died several weeks ago.
Air conditioning meters, call records and possible past complaints will be investigated to determine whether animal cruelty or neglect was a factor in this case.
Necropsies are being performed on several of the dogs to hopefully confirm the cause of death. Some of the dogs' remains have been sent to the University of Arizona and the University of Michigan to test for any chemicals.

"I think you know my record...We get the evidence and we take action," Joe Arpaio said about animal cruelty cases.
It is unclear if any charges will be filed.
Some pet owners said they have contacted lawyers to pursue a possible civil case against the Hughes', who were vacationing out of state when the dogs died.
Sheriff's officials said the couple arranged for the dogs to be taken care of by their daughter and their son-in-law.
The son-in-law, Austin Flake, is the son of U.S. Sen. Jeff Flake, R-Ariz. The senator issued a statement calling it a "tragic accident" but didn't confirm or deny his son's involvement.
Arpaio said the owners of the kennel, as well as Austin Flake are not cooperating with the investigation.
