How do I choose the right size for my pet?
Measure your pet’s back length and chest girth before buying — weight is just a reference. If the back fits but the chest is smaller, go one size down. The backpack suits calm pets that enjoy close rides.
My dog gets nervous in carriers. Will this backpack make him uncomfortable?
Most pets feel calm in Mosago’s open, breathable design. Their legs and tail hang out naturally, so they don’t feel trapped. Many even fall asleep during walks or rides.
Is it safe? I’m worried my dog might jump out.
Yes. Mosago’s triple safety system—zippers, Velcro, and an inner buckle—keeps pets secure. The anti-escape zipper only opens when lifted.
Will it hurt my shoulders if I carry for a long time?
No. The wide padded straps and thick bottom cushion distribute weight evenly. Even small dogs up to 15 lbs feel light and balanced.
