How much to feed
How much should I feed a dog that lives mostly outdoors on a farm?

Short answer
A dog living mostly outdoors, especially through cold weather, generally needs more food than an equivalent indoor pet, often 20 to 30 percent more in cold conditions, because maintaining body temperature outdoors burns additional energy on top of normal activity. The exact increase depends on climate, coat type, and how much shelter the dog has, so treat the standard indoor calculation as a starting point to increase from rather than a fixed final number.
Why outdoor living increases food needs
Dogs that spend significant time outdoors in cold weather burn extra energy keeping warm, and this effect is larger for short coated breeds than for those with a thick double coat suited to the climate.
A dog with adequate shelter from wind and wet weather needs less of an increase than one more fully exposed to the elements.
Working out the adjustment
Start from the standard calculated amount for the dog's weight and activity, then increase by 10 percent as a first step during cold weather, watching body condition over two to three weeks before deciding whether more is needed.
In genuinely harsh winter conditions, some working and outdoor dogs need 30 percent or more above their summer amount, dropping back down again once the weather warms.
Other practical considerations
Make sure water does not freeze and remains available, since dehydration affects appetite and overall condition regardless of how much food is offered.
Check body condition through touch rather than sight for thick coated breeds, since a heavy winter coat can hide both weight loss and weight gain from a casual look. Revisit the amount again once warmer weather returns, since the extra winter allowance is not usually needed for the rest of the year and can lead to gradual weight gain if left unchanged.
Key takeaways
- Dogs living mostly outdoors, especially in cold weather, often need 20 to 30 percent more food than an equivalent indoor pet.
- The exact increase depends on climate, coat type, and the quality of available shelter.
- Increase gradually in cold weather and reduce again once the weather warms.
- Check body condition by touch for thick coated breeds, since a heavy coat can hide changes.
