Sorry St Bernards!
For a jet-setting star like singer Katharine McPhee, having portable pets is key.
Luckily, the former American Idol finalist has two great little globetrotters: her Chihuahuas, Nena and Larry.
"They're the most amazing travelers, and they're tiny, which helps."
Though Nena and Larry's small stature allows them to travel with ease, it also means extreme weather can have a big impact on the pups.
"They aren't great in the cold. I was just in New York, so they haven't been traveling with me most recently. In L.A. cold weather? People complain that it's freezing, but it's really not that cold, and my dogs can handle it. But in New York it's legitimately cold, so they actually need the sweaters."
We wanna see those!
