HOUSTON – The number of dogs reported sick from dog jerky treats has increased. In March, 600 dogs were sick. That number has since gone up to 1,000 dogs. The three brands of dog treats cited for the illnesses were Waggin' Train, Canyon Creek Ranch and Milo's Kitchen Home-style dog treats. The agency sent inspectors earlier this year to Chinese plants that make the jerky treats, but the results of those reviews are not available yet.
