Dog is 'perro' and bad is 'malo' so I guess 'perro malo' or maybe 'malo perro'. A computer translator gave me 'mún perro' but either I don't understand enough Spanish or that's not right.
perrito
Mi perro.
There are two ways that you can say "too bad" in Spanish, lástima or ¡qué pena!
perro negro
pobre perro
perro
Perro.
To say My dog likes to eat dog food in Spanish, is:Mi perro gusta comer alimentos para perros.
Me falta un perro is the best way to say "I am missing a dog" in Spanish.
perrito
perra
Mi perro.
su perro
hembra
hembra
Mal
No me gusta perro
