A recent article about a wave of Parvo in Michigan for all dog owners to read and be aware. Until more is known about this illness, extraordinary caution might include avoiding walking dogs (and especially puppies) in public places in Michigan, and keeping your dogs away from other dogs. Most importantly, if you live in or have traveled through Michigan, or your dog has been exposed to dogs who live in or have been taken through Michigan recently, and your dog or puppy shows any signs of being ill with vomiting, diarrhea, lack of appetite, or lethargy, contact your veterinarian right away.
