About 800 small dogs, including Chihuahuas, terriers and Pomeranians, were seized from a large mobile home whose occupants were overwhelmed trying to care for the animals, authorities said. Pima County sheriff's deputies and animal welfare officials who removed the dogs also found 82 caged parrots in the home in a rural area northwest of Tucson. Some dogs were pregnant and giving birth as they were taken to shelters in Tucson, said Jenny Rose, a spokeswoman for the Humane Society of Southern Arizona. Ninety-six dogs were taken from the house Monday and another 700 on Wednesday, she said. "The home was definitely in very bad condition, urine and faeces all over the home, in the kitchen and bedroom, with a very strong odour," she said. "Obviously, 800 dogs in a triple-wide mobile home, they were packed in there. That being said, they were in pretty good shape." A triple-wide mobile home is made from putting together three tractor-trailer-sized units. The elderly owners, who have not been identified, were apparently overwhelmed but have cooperated with authorities, sheriff's Sgt. James Ogden said. No charges have been filed, but authorities continue to investigate. The animals appeared to have had enough food, but a few were missing paws - some from having been attacked by other animals, others apparently having caught their feet in fencing outside, Rose said. The breeds included Chinese cresteds and Lhasa apsos. The owners were breeding and offering the dogs for sale, Rose said, but she described it as a hoarding case, in which elderly people sometimes feel no one else can give their animals a good home and won't part with them. Deputies were alerted this month after a woman who bought a Chihuahua at the home reported the conditions, Ogden said. The dogs living inside the house apparently had free run of the premises, Ogden said. Others were found in other structures on the property. Ogden described the living conditions as "horrible, filth everywhere ... probably one of the worst (situations) I've ever seen." The animals will be offered for adoption soon, Rose said, adding that a rescue group from Phoenix had taken 100 of the dogs.
