Thin ice, ponds and dogs in winter
Cape Ann winters freeze and thaw so often that pond ice is rarely as solid as it looks: a cold week sets a skin over Niles Pond or a quarry pool, then a mild day softens it from below. A dog chasing a gull or a skidding ball does not read ice. This page covers why the ice lies, the first minutes after a dog goes through and the leash habits that stop it happening.
Why ice fails
Pond ice on Cape Ann is unreliable because of thaws, snow cover and moving water
MassWildlife's ice guidance begins by telling everyone to treat all ice as potentially dangerous, since appearance and thickness alone cannot show its strength. Depth, the size of the pond, currents, snow cover, the age of the ice and the weather all change it, and a foot of old, partly thawed ice may not hold what four inches of new clear ice will. White or snow ice, it adds, is only about half as strong as clear ice.
Moving water is the other trap. MassWildlife warns that ice over currents and springs is often thinner than it looks, and the state's 2022 joint safety release adds that snow insulates ice and hides cracks, and that ice can be a foot thick in one spot and an inch thick in another. Tidal creeks in the marshes along the Annisquam and in Essex freeze at the edges, but the tide keeps water moving underneath.
- All ice treated as potentially dangerous, as MassWildlife advises
- Snow cover insulates the ice and hides cracks
- Ice over currents, springs and tidal creeks is weakest
- A foot thick in one place, an inch in another
If it happens
If your dog goes through, call 911 and stay on the shore
MassWildlife's instruction for a pet that falls through is blunt: do not attempt to rescue it, go and find help, because well-meaning owners easily become victims themselves. The 2022 release from the state police, DCR, the Department of Fish and Game and the Environmental Police tells the public to call 911 when a person or a pet goes through the ice, and to call for help before attempting any rescue.
While you wait, help from solid ground. The same release says to use something long or throw something to the victim while first responders are on the way. MassWildlife tells people who fall in to turn back the way they came, because that ice has already held them, and the same logic applies to a dog: keep calling from the point where it walked out, so it swims to that edge rather than toward you across unbroken ice.
- 01
Call 911 at once and give the pond's name or the nearest street
- 02
Stay on shore and do not step onto the ice, however close the dog looks
- 03
Call the dog toward the edge it walked out on, where the ice already held it
- 04
Reach with a long branch, or throw a leash or rope, only from solid ground
- 05
Once the dog is out, wrap it in a coat or blanket and get it into a warm car
- 06
Call your vet on the way, and get yourself warm and checked if you got wet
Prevention
A leash near frozen water is the whole prevention plan
Both state releases give the same instruction: keep pets leashed on or near ice. The ASPCA adds that a dog should never be off leash on snow or ice, especially in a snowstorm, because dogs can lose the scent in snow and get lost. On Cape Ann that means the leash goes on before you reach the water at Niles Pond, the reservoirs and the flooded quarries, and stays on until you are back on the road.
Some places settle the question for you. Halibut Point State Park's rules forbid swimming in or entering the quarry for any reason, and the park is not on DCR's list of off-leash properties, so dogs there stay on a leash of no more than ten feet. Skip fetch near frozen water, because a ball that skids onto the ice invites the dog to follow it. A recall trained on a long line is the backup, not the plan.
- Leash on before the shoreline at every frozen pond and reservoir
- No ball or frisbee games near frozen water
- Halibut Point: no entering the quarry, and a leash of ten feet or less
- Off-leash dogs in snow can lose their way, the ASPCA warns
Afterward
A dog pulled from icy water needs warming and a vet, even if it shakes off and runs
A dog that has been in freezing water is at real risk of hypothermia, and the AKC's advice for any suspected case is to bring the dog somewhere warm and contact a vet immediately. The mild stage shows as shivering and curling up; sluggishness, slowed reflexes and paleness mean it is getting worse. Keep the dog still, wrap it in a dry blanket or coat, and run the car heater on the way.
Call your vet as you drive, and if your clinic is closed, call the nearest emergency hospital; Massachusetts Veterinary Referral Hospital in Woburn is open 24 hours. Tell the vet how long the dog was in the water. If you went in yourself, MassWildlife's advice is to change out of wet clothing, get warm and seek medical advice; a person who has been through ice needs checking as much as the dog does.
- Shivering after the rescue: dry it, wrap it, warm it
- Dull, slow or pale: the vet, straight away
- Tell the vet how many minutes the dog was in
- Wet owners: dry clothes and medical advice
Where we fit
On iced-up weeks, a solo walk from home or a daycare day keeps the dog off the ponds
Our at-home walkers take one dog at a time from your door: 20 minutes for $25, 30 for $35 or 60 for $55, with a photo and a note after every walk. Tell us at the evaluation which ponds or reservoirs lie near your street and whether your dog chases birds onto ice; the route is planned around your address. Whether we can walk your street depends on the address and the season, so ask first.
A daycare day gives a winter dog a proper run on turf and the indoor play floors at 210 Eastern Ave: $42 for a full day, $33 for a half, in a matched playgroup of 7 to 10. From Rockport, Gloucester, Essex or Manchester-by-the-Sea, the Pup Van brings the dog over for $10 each way. New dogs need the free evaluation first, weekdays between 6:30 and 9:30 AM, with Rabies, DHPP and Bordetella on file and a current city license.
At Dogtown
