How much weight should a puppy or senior dog carry?

Very little, and for some dogs, none. A puppy's joints are still growing and a senior's may be worn, so this is exactly the case where your vet's answer beats any rule of thumb. An empty pack still gives them the job and the fun.

How do I start adding weight to my dog's pack?

Start with the pack close to empty — a couple of light items. Add a little weight every few hikes, keep both saddlebags even, and watch how your dog moves and recovers. If they lag, pant harder than usual, or seem sore after, take weight back out.

How Much Weight Can a Dog Carry in a Backpack?

AlphaPak · Reviewed by our veterinary and formulation team · Updated August 26, 2026

The rule of thumb you'll see everywhere is 10 to 25 percent of body weight. Treat that as a ceiling for a fit, conditioned adult dog — not a starting point. Start with an almost-empty pack, add weight over several hikes, and ask your vet for a number specific to your dog.

How much weight can a dog carry?

The rule of thumb you'll see from trainers and gear makers is 10 to 25 percent of body weight. Read that carefully: it's a ceiling, not a target, and it assumes a fit, conditioned adult dog on friendly terrain.

The honest answer is that it depends on your dog. Age, build, conditioning, and the trail itself all move the number. A young dog in hiking shape is a different animal from a couch regular or a senior. That's why the best number comes from your vet, who knows your dog's joints, weight, and history.

Start near empty

Whatever number you land on, don't start there. Load the pack with a couple of light items — a rolled-up waste bag, a snack — and let your dog get used to moving with it. Add a little more every few hikes.

Keep the two saddlebags even. A lopsided pack pulls to one side, rubs, and tires your dog faster than the weight itself. Water is the classic pack load, and the Kobuk bladder that comes with our packs rides flat in a saddlebag.

Watch your dog, not the scale

Your dog can't tell you the pack is too heavy, but they'll show you:

Lagging behind when they usually lead
Panting harder than the effort explains
Sitting down on the trail, or resisting the pack at the trailhead
Stiffness or soreness after the hike

Any of those means take weight out. There's no medal for a maxed-out pack — the point is a dog who loves the job.

Build it like training

Think of pack weight the way you'd think of your own running mileage: small increases, spread over weeks, with easy days in between. Condition first, load second. New to packs entirely? Start with how to use a dog backpack — getting your dog comfortable comes before any weight at all.
