State animal welfare officials say many of the 75 dogs and more than 20 birds removed from a Wilton home last week were living in unsanitary conditions and were sick. Animal Welfare Program Director Liam Hughes told the Sun Journal, on Thursday that the investigation is still open. The resident has not been charged. Court records indicate a majority of the dogs were deemed very thin or emaciated. Some had dental disease, hair loss and scabbing from chronic flea infestations, overgrown toenails, ear and eye infections and long hair matted with feces. Many had parasites. Among the dog breeds were dachshunds, pugs, Pomeranians, French bulldogs and shih tzus. There were seven parakeet-type birds, six lovebirds and four canaries as well as chickens. They have been taken to a shelter.
