Awesome, I hope he gives your mother (and the rest of the family) as much happiness as our little mutt does us
I suspect given the two breeds involved that he's going to be both quite smart, and very energetic

Our (well my mum's really) toy poodle is sharp as a tack most of the time, but quite a relaxed beastie - small pedal bins are not safe from him since he learned to open them.
I'm guessing your mum is going to be spending a fair bit of time grooming that bundle of fur

(he actually looks like our mutt does sometimes after a visit to the proper groomers, rather than us with the brushes and a shaver).
