I have a Shih Tzu from a similar background, and we love her to bits!
We have always had dogs but she's our first Shih Tzu, but she certainly won't be our last 😀
They are definitely stubborn - she has to be lured rather than ordered to do things, and she has a 'what's in it for me?' look. She has struggled with house training as she was an ex-breeder and kept in a shed (grr) but is now fine, but I understand that they often are difficult to toilet train as they are stubborn.
We keep her clipped as we live rurally and have muddy or sandy walks, so she has a rolling eight week appointment at the groomers.
She is very playful, likes a lay in, gets bored with walking after an hour and needs to go back on the lead (DH says it's like a child wanting to hold hands 😆), would like to be hand fed each meal (fat chance), and is utterly adorable.
She loves walking in the sea, trying to get other dogs to chase her, tripping me up, looking in my bag when I get back from the shops to see what I have for her...
She gets hot in the summer so we cut short her walks and limit it to early or late, and always have water and a bowl with us. Even so, she will find a muddy puddle to lie down in to cool her tummy 😆
Can you tell I am smitten? I would say, do it!
