Honestly, you can't just get the parrot... You just have to cross your fingers and hope you got a parrot as apresent your dog picks up. Or you could ask your friend if your dogs can meet and exchange items! "as gifts"
EDIT:
The text above is wrong. But to the questioner, what parrot do you mean? I don't believe in parrots during walks. But I've heard people talking about parrot on walks. But I doubt that. I've never seen a parrot on walks. But I heard you need your eyes peeled open and try to find a swooping bird around the street. Then tap on it.
I've heard of talking birds. You need to get extra trainer points to get that on Discount Shops. You don't get the talking bird during walks, however.
it eats you
You have to find a firefighter hat on walks
well i know you find it on walks or by trainer points i dont really know :(
go on walks and your dog will eventualy find it
You can't actually find the talking parrot on nintendogs. It'll be in one of the shops when you get quite a lot of trainer points, and it's awesome! when you get it, make sure you talk slow, or else you won't be able to tell what you're saying. You don't unlock anything, but it's great fun!
No you find the book on walks the "?" box
On Walks, Finding Presents
All you need to do is go for walks and try to get as many ? boxes as you can. And eventually you will find a rose.
You Don't Unlock Them, You Find Them.
You can't
You have to go on many walks and get the ?'s. And look for hidden presents that arn't on the map.
Buy them at discount shops or get presents of walks.
