MOUNT VERNON, Wash. -- Nearly 200 dogs were confiscated from two separate kennels south of Mount Vernon after authorities served search warrants for animal cruelty and neglect, Chief Criminal Deputy Will Reichardt of the Skagit County Sheriff’s Office said.

More than 400 dogs were being held in a Mountain View Road puppy mill where they had been kept in small kennels. Many of the dogs were heavily matted and were standing in their own feces in wire cages, Reichardt said.

The dogs were mostly Chihuahuas, Shih Tzus, poodles and Yorkshire terriers.

SLIDESHOW: Neglected Dogs Removed From Breeding Operations

There was also a room that was housing about 20 female dogs that were nursing litters of pups.

Seven dogs were found lying dead in a plastic crate and four dogs needed immediate veterinary care.

About 25 volunteers removed about 150 dogs Wednesday that were evaluated to be in need of better care.

Those dogs were taken to a temporary shelter at the Skagit County Fairgrounds in Mount Vernon or to the homes of volunteers.

Another 40 dogs that were living in small crates, many of which were contaminated with their own feces and urine, were seized from another location on West Big Lake Road, Reichardt said.

The dogs were mostly Australian shepherds. They are being housed temporarily in private residences of local volunteers until other accommodations can be made.

Reichardt said two ponies were also seized as they showed significant signs of malnourishment and neglect.

No one has been arrested in either case, but charges may be forthcoming, Reichardt said.

The group Saving Pets One at a Time is helping the dogs. People interested in volunteering or donating can find out how at the group's Web site.
