I just sold TWO "teapot" sisters, weighed in a 9# each, they went in the SAME large Sherpa carrier, traveled on Southwest, both the pups fit into the carrier comfortably. No room for running and playing, but they were calm and polite and could stand up and turn around...no problem, and my owner sat in the middle seat because she said that seat has the largest space under the seat. Those soft sided carriers work better I think...they "give" a little when placing the carrier under the seat in front of you....unlike the rigid carriers. |
