Cold Water in December: How Long a Labrador Can Work

A Labrador in good condition can work a shallow slough for roughly 20 to 30 minutes when the water sits near 35 to 40 F, and less than that when wind pushes the chill deeper. The clock is not the rule. The dog's coat, body fat, and behavior are the rule. On the northern plains in December, the retrieve gets called off when the dog stops shivering, slows its exit from the water, or loses interest in the bird.

How cold is too cold for a Labrador to swim?

Water below about 32 F is the hard stop for most working retrievers. Between 32 and 40 F, a lean, hard-going dog has a short window, often 15 to 25 minutes of actual water time in a December slough. Above 45 F, a healthy adult Labrador can handle longer sessions if it is dried and warmed between retrieves.

Air temperature matters less than wind. A 25 F morning with no wind is easier on a dog than a 35 F morning with a 15 mph northwest wind. Wind strips the insulating layer of air the coat holds. A wet Labrador in a 15 mph wind at 30 F loses heat fast, and the slough edges freeze first, which cuts the dog's footing and forces harder work on every exit.

The dog's own build sets the range. A Labrador carrying good body fat and a full double coat holds heat longer than a lean trial-condition dog. A dog that has been run hard since August is fit but has less insulation. A dog that has been kenneled and fed heavy has more insulation but tires sooner. Neither one is wrong. The handler has to read the dog in front of them, not a chart.

Coat condition is the other half. A dry, dense undercoat sheds water and traps warmth. A coat soaked through from a long retrieve, or matted from weeks without brushing, loses that advantage. Hunters who run hardy hunting breeds in cold marsh country know the difference between a dog that shakes off and a dog that stays wet.

What are the signs of hypothermia in a retriever?

Shivering is the first sign, and it is normal. Shivering that stops is the warning. When a dog's core temperature drops far enough, the body quits the reflex, and the dog looks calm. That calm is the danger.

Watch for these in order:

• Strong shivering, then shivering that fades or stops
• Slow, stiff movement on the way out of the water
• A tucked tail and a hunched back
• Ears and feet that feel cold to the hand
• Refusing the next cast, or turning back toward the truck
• Pale gums, or gums that feel cool
• Stumbling, or a blank look when the handler calls

A dog that stops shivering in 35 F water is done. Pull it, dry it, and get it into a warm box or against a human body. Do not send it again that day. A dog that shivers hard and keeps its drive is still working, but the handler should shorten the next retrieve and watch the exit.

How long can a dog actually work a slough in December?

A working rule for the northern plains: 20 minutes of water time in 35 to 40 F water, 15 minutes in 32 to 35 F water, and no water work at all below 32 F unless the dog is retrieving from the edge and staying dry above the chest.

Break the time into retrieves, not one long swim. Three or four short marks with a dry-off and a warm-up between them beat one long retrieve. A dog that runs three 4-minute retrieves with towel-downs in between stays warmer than a dog that swims 12 minutes straight.

Wind changes the math. Add 10 mph of wind and cut the time by a third. Add 20 mph and cut it in half. A slough with open water on the upwind side and ice on the downwind side is the worst setup, because the dog exits into the wind and the ice cuts its feet.

Depth matters too. A dog swimming in chest-deep water keeps its back and head dry and loses less heat than a dog swimming in water over its head. Shallow December sloughs in the Dakotas and Nebraska often let a dog work with only its legs and belly wet, which stretches the window to 30 minutes or more.

How do you dry a working dog after a cold retrieve?

Dry the dog before it cools, not after. The first two minutes out of the water decide how the rest of the morning goes.

1. Get the dog out of the wind. A truck bed, a blind wall, or a stand of cattails works.
2. Towel the belly, chest, and armpits first. Those areas hold water against the skin.
3. Towel the ears and the inside of the hind legs.
4. Put the dog in a coat or a dry blanket if it will stand still.
5. Offer water, not a big meal. A hard-fed dog in cold water can bloat.
6. Check the feet for ice balls between the pads.

A dog that is wet and standing in a 20 mph wind is losing heat the whole time. A dry towel and a windbreak are worth more than a longer break. Some handlers carry a small piece of closed-cell foam for the dog to stand on, which keeps the feet off frozen ground.

When do you call the retrieve off?

The retrieve is over when the dog tells you, not when the clock does. Stop on any of these:

• Shivering stops
• The dog slows on the way out of the water
• The dog refuses a cast it would normally take
• The dog's ears and feet feel cold to the hand
• The dog stands with a tucked tail and a hunched back

One more retrieve is not worth a case of hypothermia. A Labrador that goes down in cold water is hard to carry out of a slough, and the northern plains in December do not offer a quick warm-up. The dog that works again next week is the dog that got pulled early this week.

What to carry in December

A December slough bag for a working Labrador holds a towel, a dry coat, a windbreak, a thermos of warm water for the dog, and a way to check the dog's temperature if the handler has one. A dog's normal temperature runs 100.5 to 102.5 F. Below 99 F is a problem. Below 95 F is an emergency.

Handlers who run cold water should know their dog's normal temperature before the season starts. A cheap digital thermometer and a little practice make the decision easier. The dog cannot say it is too cold. The handler has to read the signs and call it.

The short version

A Labrador in good coat and condition can work a December slough for 15 to 30 minutes, depending on water temperature, wind, and depth. Water below 32 F is a stop. Shivering that stops is a stop. Dry the dog before it cools, break the work into short retrieves, and pull the dog while it still wants more. The next hunt is the one that matters.
