best purchases I have ever made…. it served more purpose than I ever imagined. My Dog travelled in this on the train, she would climb into it sometimes in the hotel room and go to sleep in it, she also did this when I was out with her and when she needed breaks from walking (due to her age and issues with her back legs) I was able to carry her. I found it comfortable using the straps over the shoulder, like a handbag. However, due to my dogs weight and size I could not tolerate the across the body straps option. I tried it twice and found it to painful and a struggle for me. But this wasn’t an issue as I found it very comfortable using the carrier on the shorter straps over my shoulder. I would frequently hear my dog snoring away when I was walking and she was in the pet carrier. She just loved it and was so relaxed in it. I’ve even been using it with her now we are back home. Honestly so happy with how this turned out. Read LessRead less about I bought this for my 12 year old, 7kg,
