The one onthe right is what?,because i have the same dog but unsure about the breed

[@DcHuff97]

He is a chihuahua and jack Russell mix (the brown one)

Ricardo Martinez the black and white dog is a Jack Rat Terrier ( which is a Jack Russell and Rat Terrier mix) I have the same dog too, it also took me a while to figure out what kind of breed he was.
