Seal Pup Birthing Season South Puget Sound, Late June - September Harbor seal pups grace our lives by visiting inland Puget Sound shores in early summer and fall. However, along the coastlines of Washington and Oregon, they are born as early as April (view map of pupping season). The pups "haul out" to get much-needed rest and warmth by sleeping on beaches and shoreline rocks, often alone for long hours. These pups are extremely vulnerable at this time and need our protection to help them survive; only 50% of harbor seals survive their first year.
Please make sure your dogs are leashed at all times when you visit the beach. Not only are the seal pups at risk from dog attacks, but dogs are at risk, too. Seals carry communicable diseases which your dog can contract, even by just getting too close. In most cities, dogs are not allowed on the beach. Virtually every year, seal pups are severely injured or killed in South Puget Sound by off-leash dogs. Don't touch seal pups! It's the law. Never handle a seal pup. They are wild animals and can inflict a severe wound. They can also carry diseases that are transmittable to humans and touching a marine mammal is a violation of the Marine Mammal Protection Act (MMPA).
Never move or feed a seal pup. If a pup is still nursing and the mother cannot her offspring, he will starve. A pup's digestive system is designed only for mom's rich milk or foods in their natural ecosystem - not peanut butter or cans of tuna fish (true instances of misguided human interference).
Stay back. Harbor seal mothers are very shy and will not return ashore for young if they feel it is not safe, so always observe from a distance. NOAArecommends a minimum of 100 yards. Human disturbance can cause abandonment of newborn pups. Approaching not only by land, but by kayak or other watercraft can have dire consequences. Read our boater guidelines here. Stay away from haul-outs, where seals gather in numbers to breed, give birth and nurse their young.
Weaned pups need protection and rest, too, since they are now on their own without mom's rich milk for survival. A pup that is scared back into the water, wasting precious calories, will be weak and more prone to low body weight, parasites and predators. Please give them space. It is against Federal and Washington State law to feed, touch or move seal pups (read more about common mistakes punishable by law on Seal Sitters' Blubberblog). Since harbor seal pups do come ashore to regulate their temperature and gain the strength required for their survival, a pup that is alone onshore is not necessarily abandoned or sick. Call your local stranding network to report marine mammals on shore.
