I really liked the goods, the size for the Corgi took the HL it I have a small 12 kg. In general, it is convenient, I do not know how the dog itself, but I think it's the best that you can think of. A little confused about the side, they are made of rubber, I think they will not last long, but we'll see. In general, I am happy with both color and quality.
Please note that XL is for 15 kg dog maximum! These bags perfectly fit dogs from the smallest ones till medium. For our 14 kg labradoodle I took XL and it perfectly matches. Now we can ride the bicycles together with our fluffy friend. Bag is comfortable for both: a dog and a human.
the backpack is a k9 backpack carrier dupe. it arrived within 2 weeks to SG so it was quick! I got my french bulldog a size L and he fits in nicely. the only thing I had problem with were the straps. they are too narrow and it doesn't really help support the weight of my dog behind my back (he's about 12.5kg!) Overall it is a good product for the price it's at so I wasn't expecting much. but definitely not for long rides as it'll hurt your shoulders.
