I didn't see Jack Russell Terrier on there...I have one of those! This is an actual picture of my dog Bullseye:

Dog Breeds
China ... Pekingese (small but mean, mi madre tiene uno pero no me gusta)
Mexico ... Chihuahua (another small and mean dog - I think all small dogs have to be mean or get eaten)
Alemán ... Pastor Alemán (German Shepard he is nice, tengo este perro)
Tengo un pastor alemán y no quiero otro perro a ésta altura de mi vida. Se llama Lobo.
Thank you,but I alredy have a German Shepherd, it's quite enough.. His name is Wolfie.

Most of them are the same as English with expection of German Shepard which pastor aleman. Maybe a Native Spanish speaking dog lover can give your more that are translated.
