Neighbors contacted officials about a home in Milford last month.
Officers found 25 dogs being housed outside in cages covered by a blue tarp.
They say all the animals were malnourished, cold and covered in their own filth.
They were taken to the Kent County SPCA for treatment.
"This type of hoarding issue is getting bigger and bigger, especially with the downturn in the economy. The right thing to do if you are overwhelmed with your animals is call a local shelter or the human society," Major Brian Whipple of the Kent County SPCA said.
The home's owner, Mary Carey, was arrested.
Authorities hope to have all the animals up for adoption soon.
