Pick the Right Size

A backpack that's too small limits what your dog can carry and pinches at the sides. Too large and it bounces all over the back. Measure your dog's back length from the base of the neck to the base of the tail, then add two inches for movement. Your dog should be able to lie down and walk normally without the pack tilting sideways.

Check the Weight Capacity

Most dogs should carry no more than 10 to 15 percent of their body weight. A 60-pound dog can handle 6 to 9 pounds comfortably on a two-hour hike. Go heavier and you'll see limping within a day. Most good packs list weight capacity clearly, so do the math before you load it up.

Look for Padding in the Right Places

The chest strap and back panel need padding to prevent chafing. Check if the padding is glued or stitched. Glued padding peels away after two months of regular use. Stitched padding lasts through the life of the pack.

Test the Closure System

Velcro closures work fine on calm walks but slip open when your dog rolls in the dirt or brushes through wet brush. Buckles and magnetic closures stay sealed and are faster to open when you need to grab something quickly. Avoid zippers on dog packs because one caught hair or stuck fabric ruins the whole trip.

Consider the Pockets and Attachments

Two side pockets fit standard water bottles and keep them from spilling into the main compartment. External carabiner points let you clip a leash, keys, or a small light. More pockets don't always mean better if they're poorly designed and make the pack lopsided.

Frequently Asked Questions

Can my dog carry water on hikes?
Yes, but not too much. Water is heavy at about 2 pounds per liter. A 50-pound dog can manage two liters on a three-hour hike without strain. Collapsible bowls pack flat and clip to most packs. Always refill at streams or carry extra bottles yourself.
How do I train my dog to wear a backpack?
Start in your yard with an empty pack for 10 minutes at a time. Reward heavily with treats and praise. Add small items once your dog walks naturally. Take a short 15-minute walk before jumping into a full hike. Most dogs adjust within a week.
What's the best backpack for small dogs under 20 pounds?
Look for packs with adjustable straps that cinch down tight. The Ruffwear Approach comes in XS, which works well for small breeds. OneTigris offers sizes for dogs 15 to 35 pounds. Avoid oversized packs because they'll slip and rub.
Can I wash my dog's backpack?
Most packs rinse clean with a hose and air dry in four hours. Check the manual because some have removable pads you can hand wash separately. Never throw a backpack in the washing machine because the padding will clump. Don't use the dryer.
Is a dog backpack necessary or just nice to have?
For day hikes under an hour, it's optional. For longer outings where you need to bring water, snacks, or a first aid kit, a good pack saves your shoulders and lets your dog carry a fair share. It also gives your dog a job, which most love.

Bottom Line

The Ruffwear Approach Pack is the clear winner for serious hikers. It distributes weight perfectly, the harness padding lasts, and your dog moves naturally even on rough terrain. If your budget is tighter, the OneTigris pack delivers 80 percent of the performance for half the price. Either way, a proper dog backpack makes hiking together smoother and more enjoyable for both of you.
