WDNR- The estimated 50,000 or more Wisconsin waterfowl hunters whose favorite hunting partner has four legs, a tail, and doesn’t mind swimming in cold water may want to take some precautions against their friend coming down with serious illness from ingesting water containing potentially toxic blue-green algae.
“Working together with dogs is part of a long and rich tradition for many waterfowl hunters,” said Kent Van Horn, DNR Migratory Game Bird Ecologist. “Sometimes, care of these furry hunting companions requires extra awareness. While not widespread, potential toxicity from blue-green algae is still a concern for waterfowl hunting dogs.”
Recent cases included three Wisconsin dog deaths from blue-green algae poisoning reported in 2008, two in 2009, and thankfully none in 2010.
With about 80,000 waterfowl hunters, Wisconsin has the third highest number of waterfowl hunters in the country. About 60 percent of Wisconsin waterfowl hunters use dogs to retrieve their harvested ducks and geese.
Hunters should adhere to the following advice of the Wisconsin Veterinary Medical Association to help protect their dog’s health:
- Provide a good supply of clean fresh water for your dog to drink while hunting.
- Don't let dogs submerse themselves in water that has a bloom.
- If your dog does get in water with a bloom, wash your dog thoroughly before it starts to groom or lick itself.
- Be sure to wear gloves when you wash your dog and avoid direct contact with any "algae" present.
After potential exposure, watch your dog for signs of lethargy, loss of appetite, vomiting, diarrhea or even seizures. If your animal shows any of these symptoms contact your veterinarian immediately.
