The extendable pet backpack from Fudajo makes it possible to transport small dogs or cats up to a maximum weight of 6 kg comfortably on your own back. Whether for a visit to the vet, a hike or a trip on holiday, the pet backpack makes it easy to transport your four-legged friend. The dog rucksack has a main compartment measuring 27 x 35.5 x 41.5 cm. When the rucksack is not being carried, an additional compartment can be pulled out, increasing the size of the rucksack to 59 x 35.5 x 41.5 cm. The small animal rucksack is made of hard-wearing polyester material so that the pet has a good hold in the rucksack and also to prevent the four-legged friends from accidentally escaping. This is supported by the secure zip on the entrance flap. When the item is used as a pet rucksack, the textile has three windows: firstly the entrance flap, which is also a mesh window, and secondly two transparent plastic windows on the right and left, each with two air holes. This allows enough fresh air to get into the dog rucksack and the four-legged friend has an all-round view. The extendable section has mesh windows on all three sides and the roof. The shoulder straps of the pet backpack are adjustable so that they can be customised to fit your own body. There is a small pocket on the side of the cat carrier backpack, which can be used to carry a water bottle for your four-legged friend, for example. The pet rucksack allows you to spend more time with your dog or cat.
