Sharing a bed with your dog could be a problem if pet allergens trigger your asthma.
Allergens in an animal's skin flakes, saliva and urine can bring on symptoms in people with allergic asthma, according to Asthma + Lung UK.
But not everyone with asthma is allergic to pets, the charity says.
The issue of pets in bed was raised by mattress retailer Happy Beds in 2023, when it advised owners to avoid sleeping directly with shedding pets.
The retailer said loose hair in bedding could cause irritation and suggested brushing pets and using tools designed to remove fur.
Some dogs and cats shed their lighter coats in autumn as they prepare for a heavier winter coat.
What to know about pet allergies
Pet allergy symptoms can include sneezing, itchy eyes or nose, itchy skin and a rash, according to Asthma + Lung UK.
People with asthma may also experience coughing, wheezing, breathlessness or a tight chest.
The charity says symptoms can begin within minutes of contact with a pet or take several hours to appear.
It recommends asking a doctor about an allergy skin prick or blood test to confirm whether a pet allergy is responsible.
Dogs that shed less hair can still trigger allergy and asthma symptoms, the charity says, and no pet is completely hypoallergenic.
Reducing exposure and managing shedding
If pets trigger your asthma, Asthma + Lung UK says it may help to limit where they can go in the house and regularly wash surfaces they touch.
It also recommends cleaning carpets regularly, ideally with a vacuum cleaner fitted with a HEPA filter.
The charity advises anyone whose asthma symptoms are getting worse, or who is using a reliever inhaler more often, to see a doctor or asthma nurse as soon as possible.
For managing a dog's coat, animal charity Blue Cross says regular grooming removes dead hair, dirt and dandruff and helps prevent matting.
How often a dog needs grooming depends on its breed and coat: a short-haired, smooth-coated dog should be groomed at least once a week, while rough or long coats need more frequent attention.
Blue Cross recommends asking a vet which brush is best for your dog, as different tools suit different coats.
If a dog is frightened of brushing, the charity suggests introducing a soft brush gently in short sessions and rewarding the dog.
Owners should seek a vet's advice if grooming problems persist.
