    My doggy backpack well made..fits my doggy inside nicely. Kinda thinking would be better with waist straps as well for extra weight support for a bit too hot just now to use it but definitely when it gets cooler.hackney dog house sent it very quickly so I would not hesitate to use they again.. thank you soon much

    Highly Recommend!

    We bought this after seeing similar ones in our local mountain bike group but all of them were from America so wasn’t worth paying the delivery, I searched for a while a came across hackney dog house that supplies these carriers and I’m over the moon with it! We take our little dachshund everywhere with us now and he’s so comfortable in it, he loves it! I had to order two sizes as was unsure what would be the best fit, the customer service with hackney dog house was fantastic, communication and arrangement of refund for the one bag that wasn’t a great fit was easy and straight forward, you know you’re in safe hands with a great company and an awesome product! Thanks all :)

    Good product

    Purchased this for my 10 week old corgi puppy since he's not vaccinated yet and he does really like it! Opted for a size large (something to grow into) and also bought one of the booster blocks. Super happy with my purchase!
