Dogs and hypothermia...some good info for cold weather hunters!

1 post in this topic

I took this from another forum...some good info here:

I once read a post where a waterfowler said, " my dog wouldn't continue to go into the water and retrieve if the conditions were too cold for him". That way if thinking can lead to a tragic situation for ANY dog.


Hypothermia and the retriever

Recognizing and treating the hypothermic canine

"....the cold, wet conditions of waterfowling are two of the most demanding environments known, and they can create a very dangerous situation for yourself and your retriever — ice.

A well-trained retriever will trust and obey you completely. This makes it our responsibility to not put our retrievers in dangerous situations. Allowing your dog to retrieve on ice is just asking for trouble. For those that do not know, ice is always thinner toward the middle of a pond or river than on the edge, and it is never a good idea to send your dog to retrieve a bird downed on the ice.

If your retriever becomes trapped in sub-freezing water, it will not take long for her to become hypothermic. Most dogs become trapped in these situations when they are not able to get back up after falling through weak ice. Constant submersion in such water temperatures only requires a few minutes for core body temperature to drop so low that you will pass out. Most fatalities from freezing water occur from drowning after their body temperatures, and ability to swim, plummet rapidly sending them to an icy grave.

That being said, it doesn't have to be freezing for hypothermia to occur. Wind chill and constant exposure can also lead to hypothermic producing conditions. Symptoms of hypothermia follow a predictable pattern. The first symptom will be shivering, as the body tries to warm itself. This will progress to weakness, stiffness, and stupor. In the final stages of hypothermia the dog may lapse in to unconsciousness or coma, possibly leading to death.

If you believe that your retriever may be hypothermic, take immediate action to warm him up. If your truck is nearby leave everything and take the dog to the truck. Warm the truck up and put your dog in the floorboard under the heat or blow the heat out the vents toward the dog on the seat. In lieu of a warm truck, build a fire to produce some heat. Vigorously rub your dog. Preferably with a dry towel, but you're not necessarily rubbing to dry him off, as much as you're rubbing to create friction and produced heat and stimulation.

If you have a thermal blanket (the mylar sheets — not the plug-in electric type) in your emergency kit, you can use this as a thermal shield to reflect the heat of a fire or create a small warming chamber in the truck. This is much more effective than simply wrapping him up in the blanket. Of course, if no heat source is available or you will need to carry him a long distance to a vehicle, wrapping him is beneficial and will help trap body heat. If this is the case, even if you have him wrapped continue to rub vigorously to warm and stimulate him through the blanket.

You will know that you are making some progress by watching symptoms reverse themselves until eventually your retriever beings to shiver. This means that the temperature have risen to the point that the brain once again recognizes that he is cold and needs to warm up.

Most long-term hypothermic damage occurs to organs (such as the brain) that have not received adequate blood flow during the event, in which case it may be several days or weeks before you or your veterinarian know the entire extent of the damage.



Canine Hypothermia Part 1

".... It doesn’t have to be frigid conditions for a dog to show signs of hypothermia, exposure in cold water with some wind is all that is needed. Over the next few days we will discuss the signs and symptoms of canine hypothermia, the treatment if your dog is showing signs, and common sense ways to prevent it; but first I want to provide some basic information of what hypothermia is

Hypothermia is when the core body temperature drops due to exposure to cold. It can be deadly if ignored. A dogs normal body temperature is 101-102 degrees Farenheit. Hypothermia occurs once a dog’s temperature, taken with a rectal thermometer, drops below 97 degrees. The temperature outside does not have to be below freezing for this to occur. In fact studies have show that 55 degree water, with 40 degree air temps and 10 mph winds are prime conditions for hypothermia to occur in a dog. Most of us duck hunters have all hunted in much worse conditions than these. Check back throughout the week as we will take an in depth look at how to protect our hunting partners from this deadly condition.


Canine Hypothermia Part II- Signs and Symptoms

Hypothermia can be divided into 3 categories or stages.

1) Mild: The dog begins to shiver and connot control the shivering. Your dog will begin to act lethargic or tired. Typically at this stage the dogs temperature is between 96-99 degrees F.

2) Moderate: Once a dog’s temperature falls into the 90-95 degree F. range it lose it’s ability to shiver. The dog will lose coordination and appear clumsy, at this point the dog may lose consciousnous. If it gets to this point, your dog life’s is in serious danger.

3) Severe: 82-90 degrees F. At this point your dog will have collapsed, it will have trouble breathing, the pupils will be dilated and the dog will be unresponsive. If hypothermia gets to this point it is critical that the dog be warmed quickly and taken to an emergency vet center.

Like most things, if you pick up on the signs early, it is very treatable and will have no long suffering effects on the dog. Keep and eye on your pup when it’s cold out so you can be sure he can share the blind with you again next time.


Canine Hypothermia Part III- Treatment

So now that we know what the signs and symptoms are we notice that are dog is shivering and seems clumsy and uncoordinated. Hypothermia is suspected, so we grab our Field First-Aid kit and check the dog’s temperature; it’s 94 degrees F. What now?

At this point the number one factor is to remove the dog form exposure to cold, and prevent any further heat loss. For most of us duck hunters that will mean drying the dog. Use towels, your coat, anything you can that will absorb the water from the dog. The next step is get the dog out of the wind. If you are in a blind this will not be too difficult, but if you are hutning from a boat or in flooded timber you may want to use your coat to make a wind block for the dog. Body to body contact can help as well. This doens’t mean you have to get naked and huddle with the dog, but pulling the dog close or opening your coat and huddling with the dog will help the dog warm up. If you can get the dog to your truck, put the dog in the floor board, crank the truck and use the heater. This is about all that can eb done in the field, but anytime you have to do any of this an emergency vet visit is needed. Once at the vet’s office their are number of things they cna do like warm fluid IV’s and flushing stomach or rectum with warm isotonic fluids.


Canine Hypothermia Part IV- Prevention

Perhaps the easiest way to deal with hypothermia and your dog is to aviod it. This does not mean you cancel those cold weather duck hunts, but a few precautions should be taken when the mercury drops.

The first thing is transporting a dog to the field. If you have a dog box, put cedar shavings in the box to help insulate it. If you use the plastic or wire crates, use an insulated kennel cover. This will keep the cold wind of the dog as you drive to your hunting location.

Once you arive, put a neoprene vest on your dog. The neoprene vest does a great job at keeping the body warm even when wet. There are several manufactures and several models to choose from.

Keep the dog from sitting in the water. Sititng in the cold water will zap the warmth right out of the dog; so use a dog stand or find a spot in the boat or blind that is dry for the dog to sit.

Kepe your wet dog out of the wind. You can do this buy hanging a piece or burlap or placing the dog behind a brush pile. Anything that will help keep some of the cold wind of will be beneficial.

Dry the dog often. Try and help keep the dog dry, use towles, or better yet a chamois cloth, to dry the dog off when the shooting slows down.

Keep a bumper in your blind bag. If it’s bitte rcold and the shooting is slow, throw bumper (on land) a few times and let the dog run some to retrieve it. Just getting the dog up and getting the blood flowing will help add warmth.

Hypothermia is serious and kills hunting dogs every year. Knowing the signs and symptoms, having some basic knowledge of first level treatment may one day save your dog’s life. There is no better cure than prevention, so use good sense when the temperatures are cold, and you and your buddy can enjoy a lot more cold mornings together."

      Man that is a tough situation I don't know what I would do. Maybe hold off on the mri and go like 6 weeks with strict rest and see how it goes. I would say too that I wouldn't hunt him at all this year regardless on if he seems to be better or not.

      Just wanted to see if any of you have experienced this with your hunting dogs. I have a 1 1/2 year old black lab who I’ve really been excited to hunt with this year but unfortunately that has been put on hold for the time being. When the problem occurred. Of course while I was on the road for work my wife called and told me that she was playing catch in the back yard throwing the ball maybe 20ft at max and our dog slipped and kind of rolled over himself (from what she said). After that she noticed that he was limping a little bit nothing to bad, but he didn’t want to play catch anymore. When I got home we took him to the vet who provided us with an anti inflammatory. And told us to rest him (leash only for 4 weeks). This was perfect timing because we were getting him fixed so the rest would be easy. The anti inflammatory and rest seemed like it was working at the end of the 4 weeks, my wife and I were heading out of town and we left our dog with my parents who also have a 4 year old black lab. I told my dad to take it easy with our dog due to the circumstances. When we went to pick our dog up we noticed he was limping again and I asked my dad how much activity did our dog get, he said that took his dog and our on a walk through taller grass looking for pheasants for no longer then a half a mile. So here we go again back to the vet and this time having an orthopedic surgeon look at him. They took x rays and nothing appeared to be abnormal. He recommended again 4 weeks leash only with an RX for anti inflammatory. So here we are now. It has been at the end of the 4 weeks again he seemed to be doing a little better until we had to bring him again to my parents and he was off leash for a little bit playing around with my parents older lab. And as soon as we got him back he was limping for a few days. I have told my dad servral to take it easy with our he is trying to heal. But he is the type where, ” hes a dog he will be fine in a few days. So after consulting with the vet again, they are referring us to the U of M vet clinic where we will be meeting with an orthopedic again. I kept asking our vet is this something serious enough to be needing surgery…… she didn’t think so. The guess was soft tissue damage, ie torn muscle or strained muscle. How long do these things take to heal. Basically what it comes down to is that I dont want to take him to the U of M bay $250 to meet with an orthopedic and do an MRI which is $1500 just to have them say he needs to rest more. If he has no activity for 3-4 days, the limp is barley noticeable.But anytime he is off the leash trotting around a little bit then he will limp the next day. When we work his shoulder it doesn’t seem to bother him or be an any type of pain. The first orthopedic said he got a little bit of a reaction on abduction rotation, but wasn’t to bad. Sorry for the long story but I’m getting really frustrated with the amount of money spent with basically not getting any answers.It is killing me not knowing what’s going on. Feedback would be greatly appreciated.

      Recreational netting for whitefish and tullibee is anticipated to open on several Schedule I Lakes in the Grand Rapids fisheries work area beginning in late October, according to the Minnesota Department of Natural Resources. Schedule I Lakes, which are more susceptible to sudden changes that impact water temperatures, will be opened and closed on a 48-hour notice posted at lake accesses, other public places, and the DNR website. Schedule II Lakes, will open Nov. 4. Schedule I Lakes (48 hour notice) Anticipated opening dates are as follows: Oct. 29 through Dec.4, for Deer (near Deer River) and Turtle. Nov. 4 through Dec. 11, for Side and South Sturgeon (1.75 inch mesh). Nov. 11 through Dec. 11, for Big Balsam and Nashwauk (1.75 inch mesh). Schedule II Lakes Lakes open to whitefish-tullibee sport-netting Nov. 4 through Dec. 11: Bass (north basin). Ball Club. Bowstring.* Little Bowstring. Cut Foot Sioux.* Deer (near Effie). Grave. Jessie. Maple. Pokegama. Round (near Squaw Lake –1.75 inch mesh). Rush Island. Sand (near Max).* Swan. (1.75 inch mesh). Twin Lakes (near Marble). Winnibigoshish* and Little Winnibigoshish* (1.75 inch mesh). *Bowstring, Cut Foot Sioux, Sand, Winnibigoshish and Little Winnibigoshish are designated infested waters because of the presence of faucet snails or zebra mussels. Nets and equipment used in infested waters may not be used in any other waterbody unless they have been dried for 10 days or frozen for two days. Fishing regulations require that: A whitefish netting license is purchased. A person may use only one gill net, not exceeding 100 feet in length and 3 feet in width. One end of net must have a pole, stake, or buoy projecting at least 2 feet above the surface of the water or ice. Nets must have an identification tag attached near the first float of the end that is projecting from the surface of the water or ice. Identification tags must be a minimum of 2 ½ inches by 5/8 inch permanently bearing the name and address of the owner. Identification tags for marking nets are provided by the owner. Nets may not be set after sunset or raised before sunrise. All gill nets must be set and lifted by the licensee only. Nets must be tended at least once every 24 hours. A net may not be set in any water deeper than six feet. A net may not be set within 50 feet of another net. Minimum gill net mesh size shall be no less than 1-3/4 or 3-1/2 inch stretch measure depending on the lake (see attached schedules). Nets used in designated infested waters must be dried for a minimum of 10 days or frozen for two days before using in a different water body. Nets should be dried for 10 days or frozen for two before moving from any lake to another. Nets used in spiny water flea and/or zebra mussel infested waters should be not used in any other waterbody. Nets should be transported in sealed container. Whitefish and ciscoes taken by sport gill netting may not be bought or sold. Whitefish and ciscoes taken by sport gill netting may not be used as bait. The possession limit for whitefish taken by sport gill netting within the Leech Lake Reservation boundaries is 25. Net placement should not inhibit use of the lake by other boaters. About 700 people obtain special permits to net for whitefish-tullibee each year. The DNR bases netting schedules on expected water temperatures. As the water temperature cools, game fish head to deeper water and whitefish-tullibee come to shallow water for fall spawning. Netting is allowed when there is little chance that game fish populations would be negatively impacted by recreational netting in shallow water. For more information, visit, then click on whitefish and ciscoes sport gillnetting regulations, or contact the DNR’s Grand Rapids area office at 1201 East Highway 2, Grand Rapids, or call 218-328-8836.
