Bonnie

Bonnie can be a live wire like any cheeky little dog.
She is also very affectionate & smoochy & loves a cuddle
She gets on well with other dogs of all sizes, shapes & breeds
But of course she just loves her people.
As long as you dont mind letting her inside, then outside, then inside etc etc
A doggie door would probably be a handy investment!
Bonnie is not a set & forget dog, she needs company & lots of attention to be happy
Another small dog will keep her amused & entertained, so an advantage.
She also is not a dog for Nanna..unless Nanna is active & enjoys playing, walking & getting out doors a lot!!
